Advantages of Aluminium – Aluminium is the world’s most abundant metal and is the third most common element, comprising 8% of the earth’s crust. The environmental advantages of aluminium are widely acknowledged. Aluminium is now the second most widely used material after iron due to its advantageous properties such as strength, lightness, corrosion resistance, recyclability and formability. It is being employed in an ever-increasing number of applications.
Low weight & High Strength
Aluminium is about 1/3 the weight of iron, steel, copper or brass, and is therefore an attractive material for use in applications where weight reduction is a priority. Aluminium combined with an appropriate alloy ensures steel durability.
Superior Malleability
Easy machining, aluminium is easily worked using most machining methods – milling, drilling, cutting, punching and bending.
Excellent corrosion resistance Aluminium extrusions do not rust, and the aluminium surface is protected by its own naturally occurring oxide file, a protection that can be enhanced by anodising or other finishing processes.
Electrical and Thermal Conductivity of Aluminium
It is an excellent conductor of both heat and electricity. The great advantage of aluminium is that by weight, the conductivity of aluminium is around twice that of copper
Resistance to ultra-violet rays and humidity
Non-magnetic
Aluminium is a non-magnetic material. It is often used in magnet X-ray devices to avoid interference.
Aluminium can be reused for the same purposes over and over again. Unlike many other materials, aluminium does not lose its unique properties. Extrusions are often produced with high recycled content. Aluminium as a resource is 100% recyclable.
