Aluminium : The Green Metal

Aluminium is the second most widely used metal in the world after Iron. This is owing to its unique properties such as low weight, high strength, superior malleability, easy achining, excellent corrosion resistance, and good thermal and electrical conductivity. Aluminium is also very easy to recycle.

Did you know?

Aluminium is infinitely recyclable. In fact, nearly 75% of all Aluminium ever produced is still in use today.


Aluminium extrusion process

Extrusion Log

The starting material for making aluminium mousons is the aluminium log These are cast In lengths of up to 7 metres and available in a wide range of alloys and diameters


The first operation is to cut the long extrusion log into suitable lengths for extrusion based on Press csOscIV and the final extruded length Me cut log or billet is fed into the billet heater.


Extrusion involves pressing a preheated aluminium ingot under high pressure through a Me the opening of which corresponds to the cross section of Me extrusion.


Cooling is carried out to enable the subsequent stretching and handling of the mtruded lengths Mis may be achieved with air water or a mixture of the two.

Stretching and Cutting

The long lengths are transkrrecl across the press table into the stretcher T. extrusions are then fed to the saw conveyor where they are cut to the required length


Mis is a specific form of heat treatment and typically involves heating the extrusions in ovens to a temperature which develops the mechanical properties of the extrusions like strength
