Applications and Characteristics of Aluminium Tubings

by Dave Lavoie

Aluminium is a cost effective metal that is available abundantly on earth. It is a metal that is strong, malleable, lightweight and a good conductor of heat and electricity. And it is because of all this that aluminium is the preferred metal used for making tubings.

Aluminium tubing is created through an extrusion process which is cost effective as little goes to waste in the production time. Moreover, extrusion has an affordable set up time and dies that are reusable, which saves in operational costs.

Designing capabilities of aluminium tubing

As there are no limitations to creating a die for aluminium tubing, extrusion opens the door of creativity to designers all over the world. For once, with aluminium tubings, they can design structures as they want, instead of designing structures based on the available tubings.

There are standard designs used for creating aluminium tubings. However extrusions offer versatility in design where the strength to weight property is always constant. In fact, it is this strength to weight feature of aluminium tubings that makes it a preferred choice over other metal tubings like copper and steel tubings. These metals weigh thrice the weight of aluminium and are much less malleable than aluminium.

Aluminium tubing is malleable

Alumnium is also a metal that is easy to shape and bend to any required design even in the extruded form, without any extra costs. The dies used in extrusions are only a few hundred dollars, and not like forms and casts that cost thousands of dollars. Moreover, the extrusion dies are reusable and come with a longer shelf life, less wastage and is thus cost effective in the production of aluminium tubing.

Aluminium tubing is used extensively as a heat shield, because of its heat absorption capacities and because aluminium is cheaper than other metals that can be used in creating heat shields.

Aluminium tubing is easily colored

Besides all these properties, designers love working with aluminium tubings as they can be easily colored both chemically and electronically. Aluminium naturally lends itself to be colored, and aluminium tubings give something unique to a project when colored.

It is not necessary for aluminium tubings to be only cylindrical in shape; it can also be square in shape and differ in its outer and inner diameters and alloy type. While choosing aluminium tubing, it is important to consider its pressure rating, temperature range and the maximum bend radius.

Various applications of aluminium tubings

Aluminium tubing is used extensively in various industries like the food processing, mining, aerospace, computer, medical equipment and automotive industries. It is also used in the transportation of both fluids and gases in pneumatic, process and hydraulic applications.

If you intend to use aluminium in high temperature conditions, ensure that the tubing is heat treated. Aluminium usually works well at low temperatures but can work in high temperatures only when heat treated. And if you want the tubing to be more corrosion resistant, it should be anodized. This also permits easy dying of the aluminium tubing.

With aluminium tubing being malleable and easy to shape and form, its equally easy means of connecting through rivets, nuts and bolts make aluminium tubing looks to be the most versatile tubing, and the preferred tubing in most industries.
