Why Use Aluminum Tubes By Dave Lavoie At Isnare.com Ezine Articles

Aluminum tubes are created through an extrusion process where hot aluminum is passed through a die to get the required length of tube, with constant cross section. These aluminum tubes have all the advantages and qualities of aluminum and are perfect for use in various applications and industries ranging from the aerospace to advertising industries.

It is a known fact that aluminum is one of the most versatile metals available with a combination of beneficial properties. Its high strength to weight ratio makes aluminum tubes the preferred choice for use in parts and products which should be strong, but has a low total weight.

Aluminum is found abundantly in the world, and thus is a cheap material to make tubes from. Moreover, aluminum is naturally corrosion resistant with its transparent oxide film; and through the extrusion process, aluminum tubes become more corrosion resistant through chemical and electrochemical means.

Aluminum tubes can be easily joined

Aluminum tubes, and all alloys of aluminum are easily soldered, glued, brazed, welded and even joined using rivets and bolts. In addition to this, they can be easily formed and bent, joined and machined on basic equipment using high speeds.

Aluminum tubes have many applications in products requiring enhanced electrical conductivity. This is because on the basis of weight, aluminum is a metal that is capable of carrying twice the electricity copper carries. Moreover, copper is more expensive when compared to aluminum.

In addition to being a great electricity conductor, aluminum is also a great heat conductor and can be used in heat dissipating devices. Aluminum tubes are also widely used in heat shields because of its high reflectivity.

The extrusion process is economical

Besides all the benefits of aluminum being incorporated in aluminum tubes, the extrusion process which is used for producing aluminum tubes is both economical and versatile. Through extrusion, you get aluminum tubes having a constant cross section while it is possible to create tubes of various radii.

When compared to machining, the extrusion process is cheaper. In case of machining additional costs are involved in producing each piece; however in the case of extrusion, no additional costs are involved in reproducing shapes.

When compared to welding, extruding aluminum tubes is cheap. In fact, tubes created through welding jigs cost much more than aluminum tubes. Even roll forming dies and its products are much more expensive than extrusion dies and aluminum tubes. Moreover, unlike tubes created through roll forming, it is possible to create aluminum tubes of different wall thickness through extrusions.

Design aluminum tubes according to any design

In addition to this, parts created using sand and permanent mold casting usually have to undergo finishing touches before being used. However in case of aluminum tubes, these tubes have better dimensional control. Moreover with the increase in the complexity of the parts created through casting molds, its costs increase.

However no matter how complex the design may be, there is no change in the production cost of the aluminum tubes. And when compared to the lead time of forming dies and casting molds, extrusion dies for aluminum tubes are finished with much less lead time.

With so many reasons and benefits of using aluminum tubes, there is no need of speculating why people in the construction field prefer using aluminum tubes.
