Aluminium is a light metal which can be given tremendous strength by alloying. It conducts heat and electricity, reflects light and radiant energy and resists corrosion. It is also non-magnetic, non-toxic, and can be formed by all known metal working processes. Because of these advantages it has thousands of uses.

The density of Aluminium is 2.7kg/dm³ or approximately one third the density of Steel
Aluminium alloys have tensile strengths of between 70 and 700N/mm² at low temperatures the strength increases without embrittlement in contrast to most steel alloys
At high temperatures the strength decreases . At constant temperatures over 100°C the structural strength is affected so much special consideration must be taken

Compared with other metals Aluminium has a relatively large coefficient of linear expansion. In some fabrications it is necessary to take account of this

Aluminium is an excellent conductor of heat and electricity . An Aluminium cables weighs half as much as a copper cable with the same conductive capacity

Good malleability which is a necessity for Aluminium Extruding , allows bending and other forming operations in both hot and cold conditions

Aluminium is simple to fabricate with most punching and machining techniques it is also suitable for advanced bonding and welding

As with most other metals Aluminium reacts with oxygen in the air . The oxide layer which is created is very thin , only a fraction of a micron . The oxide layer is compact and provides very strong corrosion protection

Aluminium is non toxic with its compounds found naturally in our food
