Aluminum, no rust and very light

Aluminum is one of the commonest industrial metals. It is used for
gear cases, engine crank cases, covers, fittings, and where lightness
and moderate strength are desirable.

Aluminum

is about one-third the weight of iron and about the same weight as
glass and porcelain; it is a good electrical conductor (about one-half as
good as copper); is fairly strong itself and gives great strength to other
metals when alloyed with them. One of the greatest advantages of aluminum
is that it will not rust or corrode under ordinary conditions. The granular
formation makes its strength very unreliable and it is too soft
to resist wear.

Aluminum is added to steel in very small amounts for the purpose of
preventing blow holes in castings.

Aluminum bronze, composed of copper, zinc and aluminum has high tensile
strength combined with ductility and is used for parts requiring this
combination.

Aluminum brass is composed of approximately 65 per cent copper, 30 per cent
zinc and 5 per cent aluminum. It forms a metal with high tensile strength
while being ductile and malleable.

Aluminum zinc is suitable for castings which must be stiff and hard.
