Pure Aluminium is silvery colour with metallic luster.
It is cheap and light as compared to copper, but it has much smaller conductivity and Tensile strength than copper.
It is highly malleable and ductile.
Its density is 2.7 gm/sq.cm at 20 degree celsius.
It has highest heat conductivity among metals.
Aluminium is lighter than copper.
It is good conductor of heat and electricity.
The conductivity of aluminium is 75% of that of copper.
It can be rolled, forged, drawn.
It has high corrosion resistance.
Aluminium is Cheaper than copper.
It forms useful alloys with iron, copper, zinc and other metals.
