Why is aluminium preferred to iron

A car made from aluminium is likely to be more expensive than one made from steel. Steel is widely used in the construction industry.

For example:. Aluminium has a variety of uses. Uses of iron and aluminium Iron and steel Iron is an element. Iron versus aluminium in the car industry Iron and aluminium are used to build cars. Other uses of iron and steel Steel is widely used in the construction industry. It can be cast, melted, formed, machined and extruded meaning that it can be manufactured into a variety of shapes and then subsequently fabricated to suit a whole variety of uses.

Due to its extreme versatility and strength, the use of Aluminium is becoming more popular, especially with the advantages it has to offer. Through the process of aluminium extrusion it can be supplied in ever more complex designs.

This extrusion can be supplied in a variety of finishes including anodised, mill or painted and can then be further machined or fabricated. The strength of aluminium can be adapted using varying alloying elements to provide better benefits including higher strength or easier formability. Because of its lightweight nature, corrosion resistance and ease of fabrication , aluminium sheets are the firm for projects like vehicle panelling, artwork, building cladding and kitchen fitting among other applications.

Aluminium is a corrosion resistant metal that naturally generates a protective coating. The coating formed is extremely thin and is generated when aluminium comes into contact with an oxidising environment.
