Aluminium Extrusions

Aluminium is the most abundant metal in the earth’s crust but can be obtained only in combination of bauxite. The ductility and malleability component of this metal made it an important material used in construction. It is formed according to the desired shape and design that made this metal widely used in engineering parts, aircraft construction and domestic utensils. The process that aluminium undergoes in changing its form is called aluminium extrusions.


Aluminium extrusions happen by inserting pre heated aluminium under high pressure through a die by hydraulic ram. The features of aluminium extrusions have a lot of advantages. Aside from its ductility or flexibility, it is extremely light. Its weight is about 1/3 of that of copper or steel and the preferred metal for use in the transportation industry. Another advantage of aluminium is being resistant to corrosion. This made aluminium the material of choice in construction and building industries where corrosion is common. It is an excellent thermal and electric conductor. It is the most popular for use in power transmission cables and is often used for industrial heat exchangers and automobile engine parts as a heat conductor. In spite of aluminium’s light weight ratio, it has excellent strength making it ideal for use in conditions where low weight and high strength are needed. Aluminium is an ideal material for applications such as light fittings because it is highly reflective of light. The feature of aluminium extrusions which made this kind of metal widely preferred in construction is its cost-effectiveness. Aluminium is also easy to work on, light weight and conductive to electricity and heat.


Construction and manufacturing companies have various demands on the size and shape of materials to utilize on their projects. It is a challenge for the extrusion manufacturers to meet the on-going demands of their clients. The introduction of aluminium extrusions made the production of specific material or parts easy and cost effective.
