what is aluminum used for

Aluminum is used as pure metal, in alloys, and in a variety of compounds. An alloy is made by melting and then mixing two or more metals. The mixture has properties different from those of the individual metals

Aluminum is used in a huge variety of products because of its particular properties. It has low density, is non-toxic, has a high thermal conductivity,excellent corrosion resistance and can be easily cast, machined and formed. It is also non-magnetic and non-sparking. It is the second most malleable metal and the sixth most ductile.

Associated Uses of Aluminum
Saucepans, cooking pans and pots
Soda cans
Automobile parts
Production of Boats and Ships
Paint Tubes
Components in Airplanes
Aluminum recycling

It is often used as an alloy because aluminum is not particularly strong. Alloys with manganese,copper, magnesium and silicon are lightweight but very strong.These elements are very important in the construction of aluminum parts.

Aluminum is a good electrical conductor and is often used in electrical transmission lines. It is cheaper than copper and weight for weight is almost twice as good a conductor.
