Aluminium Extruded Tube

extruded aluminium Tubes are metal tubes manufactured from aluminum and produced by method of extrusion.

Extrusion is a manufacturing process that is designed to produce objects (like tubing) of a fixed cross-sectional profile. The Aluminum is drawn or pushed through a die, the die is manufactured in the shape of the desired cross section. These can be created using a manufacturing process however extrusion has two main advantages:

Very complex cross section can be manufactured via extrusion.

Because the material used in this process only encounters shear and compressive stress, brittle materials can be worked with.

Hot or Cold material can be used in this process and manufacture can be continuous or semi-continuous. Semi-continuous produces many pieces whilst continuous produces in theory an indefinitely long piece.

Aluminium is not the only material that can be used to make these tubes; below I have listed some other materials and their manufacturing properties:

Aluminium: this is the most common material and can be extruded hot or cold, if extruded hot it is heated to between 300 - 600 degrees Celsius.

Titanium: is heated between 600 - 1000 degrees Celsius and is mainly used to manufacture aircraft components. Copper: heated the same as titanium is used also to create tubing, pipes, rods etc. A large pressure often more than 100ksi is required to extrude copper.

Lead and Tin: heated at a lower temperature than copper but used to manufacture the same products.

Magnesium: this is another material used to manufacture aircraft parts and is as easy to extrude as aluminum extrusion.

Some other materials include Steel and Zinc.

Aluminium Extrusion and Its Advantages

Aluminium Extrusion process is undertaken by several companies today which offer extruded products to buyers. The extrusion process is generally utilized in production. It is used to create parts of homogeneous cross-sections and is done by squeezing the material all the way through an outlet under high-pressure. Aluminium extrusions are popular all over the world since the metal is easily available on the earth's crust. Besides, aluminium is widely used in several applications and it has numerous advantages as well.

Companies manufacturing extruded aluminium products offer extruded aluminium profiles, systems and finished products and semi-manufactured components. Enterprises manufacturing aluminium products are generally in search of products that can fulfill the needs of the customers. All through the manufacturing process, manufacturers must give close attention to quality, performance, economy and precision. Aluminium extrusion is generally simple, however, it might turn complex in case the demand of customers for extruded products differ. There is an assortment of aluminium extrusion profiles today in the market and people are keener to get the best product for any particular industry. If you are in the automobile industry and are in need of aluminium extruded products you must look for certain shapes that are just the apt for your industry. A company manufacturing aluminium extruded products manufacture according to the supply orders and are capable in offering all kinds of shapes. These extruded products are fabricated and customized and are unique according to needs.

There are several advantages to aluminium extrusion.

Aluminium is a widely available metal and through constant cross section several parts can be manufactured in the most reasonable way. The process of extrusion allows taking advantage of properties of aluminium and it expands. Thus, this manner indeed versatile as you can manufacture several shapes in just a simple process.

However, you need high-tech machinery for the process and you can produce shape indefinitely without spending a fortune in preparation costs. Hence, the process is totally economical. Roll-forming dies, in case you have heard about them they are costlier than extrusion die.

aluminum extrusion products have longer life than items made from steel or plastic. Besides, extrusion is meant to be the most environmentally friendly and economical solution. Aluminium as a metal even when not compared for its extruded aluminium profiles and to weight properties. Even though it is light weight it has good strength. Aluminium is used for thermal and electrical conductivity. It is not only affordable it is also flexible in terms of shapes and size. It can adept to high temperatures and are thus preferred as utensils when used for heating water or boiling rice. It is corrosion resistant and can offer you good service over years. If you want you can easily recycle the metal. After steel all over the world aluminium is the most trusted and used metal. It can be fabricated to several shapes right from sheets, geometric shapes, to foils, tube, rod and wire.

So, if you are out there looking for aluminium extrusion profiles you can trust the process with closed eyes.

How Manufacturers Do Aluminum Extrusion?

The process of aluminum extrusion is simple and easy however it is very significant to know why extrusion is so important. In general metals like steel and aluminum is put to use in several industries, right from automobile, to telecommunication, transport, utensil manufacturing and at times even in the toy industry. Thus, both of these metals are in huge demand and find place is almost all the major manufacturing industries in the world.

Just after steel, aluminum is the other metal which is hugely popular all over the world. This can put in a manner stating that aluminum is the second most popular metal in the globe after steel. The former is widely available, has impressive properties, and is affordable, light weight, can withstand high temperatures and so on. And above all the aluminum extrusion involved in getting different shapes and forms for suppliers is cost-effective and simple. Both in US and Europe building industry and the telecom as well is highly dependent on aluminum extruded products. These products find a number of usages and are used in many applications.

So, what is aluminum extrusion profiles? This is a process through which aluminum is given certain shapes and forms. It starts with the hot cylindrical billet of aluminum which is pushed through a shaped die. The billet is cut from DC cast log and placed in heated container (450°C - 500°C). When pushed through the die the metal flows through the steel die. The die is placed at the other end of the container. Now, once the log passes it produces a section, this can be cut into shapes either in long length or short. The section is cuts according to the customized demands of the clients since the log is meant to be used for any particular industry. In certain extrusion process rectangular shaped billets. In this process only wide section sized extrusions are produced. This again depends according the demands of the supplier.

Aluminum extrusion is done for several kinds of industry and these aluminum extruded products are very commonly used in building industry. In this industry you can use aluminum in prefabricated houses/building structures, window and door frame systems, curtain walling, roofing and exterior cladding, and shop fronts. Besides, they also find place in the telecommunication and transport industry. In transport industry aluminum extruded products are found in rail vehicles, marine applications, airframes and for vehicles on the road.

So, what makes aluminum so popular? It is the versatility and the flexibility of the material that turns in so popular. Since aluminum is high temperature resistance and is corrosion resistant as well it is used to make utensils and is also used on transport vehicles. Besides, it is strong even though it is light weight and thus it is used in airframes.

So, if you are out there still deciding on selecting aluminum extruded products or some other metal you can give your votes to this metal as it is affordable and durable as well. No more second thoughts to this go ahead with aluminum extrusion and the products.

Understanding The Processes Used In Aluminum Extrusion

Aluminum is one of the most used metals in today's society - it can be found across a number of industries, such as construction and commercial, and in a number of applications, such as beverage cans and appliances. When choosing a manufacturer of aluminium extrusion for supplying the metal that you use in your workplace, however, it is important that you carefully consider which one will be best for your needs.

The manufacturer will begin by removing the aluminium from deep within the earth's crust (either as bauxite ore or feldspar). Often, the Bayer's method, Wohler's method or Hall Heroult method is chosen to remove the metal in its molten form. It is then hardened and moulded into whatever shape the manufacturer desires. When the aluminium is extracted from the earth in its solid form, it will be passed through a number of mechanical processes that are designed to give the metal its desired shape. These processes include: rolling, drawing, forging, spinning, piercing and extrusion.

Regardless of whether aluminium has been found in its molten or solid form, the manufacturer will then pass it through either a hot working or cold working process to prepare it for their customers. When using the hot working process (the most popular of the two), a billet will be heated to a temperature of over 79 degrees Celsius, which will allow the aluminium to be easily distorted and placed into its desired shape.

The reason for the popularity of the hot working process over the cold working one can be fully realized when you compare aluminum extrusion to squeezing toothpaste out of its tube. It is much easier to extrude the metal when it is malleable, meaning that it must have been heated to a certain temperature.

Finally, the aluminium will pass through an extrusion and drawing process that runs almost parallel to each other. This is the final step in the whole extrusion process and is the step that gives the metal its entire shape. Deep drawing, for example, is used give the metal a cup, conical tapered, cylinder and seamless tube shape. For less curved shapes, the drawing process is skipped.

Once you are satisfied with the processes and methods utilized by a potential manufacturer of anodized aluminum, you can begin submitting your orders with them. If, after your first delivery, you are still satisfied with the manufacturer based on the promptness of the order being filled and the quality of the aluminium that you receive, you can continue the relationship.

Advantages of Aluminum Anodizing Technology

The fast growth and widespread use of aluminum since World War II is coupled directly to the ability of anodizing processes to defend it from corrosion, improve its appearance by brightening it and offering a rainbow of colors, and also imparting ceramic-like toughness to its outer skin. Hydrated aluminum oxide is the steady form of aluminum in nature; so, unprotected aluminum exposed to air and water would corrode, forming a broken, powdery, white corrosion product. This growth of natural oxide, if not checked, will proceed as long as unreacted aluminum is exposed. It can actually be envisioned as an accelerated corrosion procedure; the difference between anodizing and the natural process is that anodizing forms a denser, constant, oxide layer.

Anodizing has numerous benefits over other coating choices. For instance, while plating and painting to protect aluminum, there will be always a barrier between the coating and aluminum substrate with these methods; the only bond between the two is mechanical. If the bond in this obstacle region is compromised by way of poor substrate preparation, mechanical damage likes scratching or gradual degradation (e.g., general corrosion), raw aluminum extrusion would be exposed and corrosion can commence.

Anodizing, on the other side, is a conversion coating method that results in a chemical link between an anodic aluminum oxide layer and the aluminum basis material, which is stronger than a mechanical bond. While painted or plated coatings over aluminum can be peeled away fastly, there is no means to separate the anodic layer from the aluminum on which it is formed. In addition to the bonding matter, paints and plated metallic layers are very softer than aluminum oxide. On the well-known Moh scale of mineral hardness, one type of naturally occurring aluminum oxide, that is corundum, is the ninth hardest out of ten. The only mineral that is harder is diamond! Keeping this in mind, it's not surprising to learn that a constituent coated with the hardest plated metal (specifically hard chrome) will wear more readily than a like component that is hard coat anodized.

Finally, the mechanism of oxide growth during anodized aluminum process results in a porous structure. This will permit further surface modifications such as:

-Dyeing to pass on nearly any color to the anodic layer

-Sealing with a lubricative stuff such as molybdenum disulfide or PTFE

-Infiltration with an adhesive for bonding applications

These factors, together with the fact that anodizing is much more economical than either powder coating or plating, point to the continued significance of anodizing as the coating of choice for aluminum in a broad range of applications. The strongest growth category for this aluminum appears to be that in the field of transportation. An estimated increase in the production of new aircraft to restore aging fleets and the auto industry's trend of raising the use of aluminum for the vehicle frames and bodies are likely to be the primary drivers of this growth. Another large category, architectural aluminum, does not seem to appear to be poised for large growth; in fact, this market might already have reached its peak.

Why Select Anodized Aluminum Cookware? The True Benefits of Anodized Aluminum Cookware

Anodized aluminum cookware is wonderful to cook with and won't warp or bend. It can be as hard as a diamond when proper anodizing methods and techniques are used. Anodizing is a method of aluminum preparation and makes this cookware stronger, and will last a lot longer.

Now, here comes an easy to understand chemistry lesson about anodizing aluminum to create fabulous cookware. Aluminum becomes stronger and more durable after the anodizing process. By putting a sheet of aluminum into a chemical bath of acetone; the acetone becomes the negative conductor of a chemical battery while the aluminum becomes the positive conductor of the chemical battery or the anode. When this process is energized, the aluminum's surface actually rusts and oxidizes. Oxidation creates a very strong coating, replacing the original aluminum. Typically oxidation will weaken most metals; but it doesn't seem to weaken aluminum. In fact, oxidation strengthens aluminium anodizing.

Recall the rusting aluminum in the chemical process? Well the rust is still part of the aluminum sheet but, because it has transformed itself, the original aluminum will not flake off under stress and will not transfer to your foods. It is sealed in during the chemical process of anodizing. This makes it quite desirable for many cooks. It is used in restaurants. This cookware is used in several food service industries, residential homes, hospitals, and industrial facilities with repeated use. Its strength and durability to heat up foods fast and cook at even temperatures is a time saver in many restaurants and bakeries. The new chemically enhanced aluminum transforms into anodized aluminum, and has become very strong and much more durable. It makes great cookware.

Anodized aluminum is now a popular material used to manufacture high-end cookware such as skillets, frying pans, and pots and pans for chef's and experienced cooks. We've long known Aluminum has a reputation of having heat evenly distributed on the bottom and sides of cookware. However, now we know anodized aluminum cookware provides a protective finish making it rust resistant, and is stronger, more durable, and as a result, more expensive.

It is utilized in several other industries outside cookware. For example satellites that circle around our Earth are protected from space debris floating because these satellites are layered with anodized aluminum. It is now recognized for its strength and durability. Other industries such as the automotive industry use anodized aluminum for trim on vehicles and for protective housings exposed on the outside of our cars. Furniture manufacturers use it for outdoor patio sets because it stands up to outside elements and weather conditions. Computers and home appliances are manufactured with anodized aluminum as a protective housing. Baking cookie sheets, pastry sheet pan, and pots and pans will be around for a long time because they will last for years using this type of cookware.anodization aluminium

The History and Future of Aluminum Extrusion

Aluminum is all around you. In fact, aluminum is actually the third most abundant element (coming in after oxygen and silicon) and far and away the most abundant metal in the Earth's crust. So it truly is all around you. However, aluminum is ubiquitous in our lives in more than just the sense that it's an abundant material.

When compared to materials like copper and steel - the use of aluminum is relatively recent. This was because until the late 1800's, when the Hall-Heroult process was developed, aluminum was quite difficult to extract from the various ores it was found in. In fact, at the time ore was even more valuable than gold. With more efficient refining processes, the availability of aluminum quickly made it an incredibly popular material.

While aluminum has most likely existed since the beginning of time, modern and ancient civilization alike have constantly found more uses for the material, which leads to the topic at hand: aluminum extrusion.

In 1797 English inventor and locksmith Joseph Bramah patented the first extrusion process, which he used to make lead pipe. His early, primitive process involved forcing the metal through a die by using a hand-held plunger. This process was expanded upon with Thomas Burr's hydraulic press in 1820, which eventually led to the creation of the hot extrusion press by Alexander Dick in 1894. What was revolutionary about Dick's press was the fact that it extended the extrusion process to most non-ferrous alloys.

With the advent of extrusion came a dramatic rise in the amount of cutting end manufacturing being done, especially in the automotive industry. But aluminum extrusions aren't just found on cars. The process has been utilized in many ways since its introduction to the world. While the earliest extrusions were various pipes and wires, modern aluminum extrusions can be found in everything from sporting goods to high tech aerospace components.

While the newfound availability of aluminum made a major impact on the industrial sector, and especially the automotive industry, aluminum extrusions would prove to be an even greater game changer later on. This was seen during World War I and World War II, where the need for rapid manufacturing of aircraft was matched by short lead times afforded by the aluminum extrusion process. Because of this, the rapid development of the extrusion process received a valuable boost that propelled its expansion beyond automotive, aerospace, and military endeavors into many other industries ranging from housing to consumer goods.

Today, the aluminum extrusion process continues to see extensive growth and continued development in terms of the materials and processes used. New methods and techniques for making the extrusion process more precise and efficient are continually being found, but the legacy of the process remains the same. If the rapid growth of the extrusion process is any indication, aluminum extrusions will contribute to innovation for years to come.
