Pure Aluminium
Commercially pure aluminium varies from about 99,3% to 99,7% Al. The higher purity Aluminium is selected for use as electrical conductors and reflector sheets. Lower-purity alloys with iron an copper added as necessary is relatively soft and ductile with excellent workability and weldability
Aluminium is an important material in a large cross section of industries. It is suitable for forming, welding and machining and provides the following advantages:
Non - Magnetic
Good electrical conductivity; about 60% that of Copper but reduced by the presence of alloying elements
Highly economic to recycle
High specific strength
High corrosion fatigue resistance
Low specific gravity approximately 1/3 of steel
Although available in a number of grades, Aluminium can be divided into two major categories of wrought alloys
