What do we get when gold is mixed with aluminium?

You can work out the actual alloy designation number by determining the amount of metal is in each example. An alloy that is 91% aluminum and 9% gold (assuming pure aluminum and gold) would be an 8000 series aluminum alloy if wrought and 9000 series if cast. read more

Copper and aluminum can be combined to form a copper-aluminum alloy. An alloy is a mixture, and therefore does not have a chemical formula. However, under very high temperature, copper and aluminum can form a solid solution. When this solution cools, the intermetallic compound CuAl2, or copper aluminide, can form as a precipitate. read more
