Uses of Aluminum
1) Low density and strength make it ideal for construction of aircraft, lightweight vehicles, and ladders.
•An alloy of aluminium called Duralumin is often used instead of pure aluminium because of its improved properties,
2) Easy shaping, corrosion resistance (to natural acids), resistance to weathering and low density make it a good material for a host of uses such as
–Food packaging (drink cans) uses anodized aluminum (aluminum with artificially thickened oxide layer by electrolysis)
–External structures such as roofing materials, electrical cables, greenhouses and window frames.
–Often electrical cables are steel-cored aluminum wires
3) Good conduction of heat leads to its use for boilers, cookers and cookware.
