The Benefits of Aluminium



As the most abundant mineral in the earth’s crust, aluminium in chemical, physical and mechanical forms, is a metal just like titanium, zinc steel, brass, copper, or lead. Aluminium has the same capabilities of being melted, cast, formed and machined, just like other metals, however, aluminium has the edge over these metals when it comes to its unique combination of attractive properties. What then makes aluminium the second most extensively used metal in the world, after steel?

  1. Light Weight

With a weight of about a third that of steel, aluminium is a very light, yet extremely stable metal. This benefit is especially useful in applications involving moving parts aluminium, climbing/access aids as well as in the transport industry.

  1. Recyclable

In addition to being a hundred percent recyclable, aluminium also does not lose its unique properties. Furthermore, the re-melting and recycling process requires only about five percent of the energy required to produce the initial primary metal.


  1. Excellent Malleability & Reflectivity

Aluminium has a low melting point and density that allows it to be processed in various ways in a molten condition. Also, it is a good reflector of visible light and heat which makes it an ideal material for reflectors.

  1. Highly Corrosion Resistant

The surface of aluminium generates a protective oxide coating when it comes into contact with oxygen from the air. This dense layer of oxide then instantaneously reforms when damaged and subsequently protects the metal underneath against corrosion, thus offering excellent corrosion resistance. This protection can be further enhanced by anodising or other finishing processes.

  1. Electrical and Thermal Conductivity

In relation to aluminium’s weight and overall cost, it conducts heat and electricity almost twice as good as copper, which therefore makes it the most commonly used material in major power transmission lines.
