different alloys are used. It depends on what the gold will be used for. but 12 kt is half gold

12 karat gold: Gold's purity is measured in 24ths. 24 karat gold is completely pure, 12 karat gold is 50% gold and 50% random other metals.
In case you're wondering, Gold = Au
Brass: Brass is an alloy, the different things it's made of aren't bonded chemically, it's what's called a metallic bond. Basically, all the electrons from a whole lot of atoms gather around the different atoms, making a kind of magnetic wall that holds the atoms together. Anyway, because of this, there isn't a chemical formula for brass. It is however made of a combination of Copper and Zinc, usually with a lot more Copper than Zinc.
Copper = Cu
Zinc = Zn
Steel: Steel is also an alloy, so it has the same problem as above. It's a mixture of Iron and Carbon.
Iron = Fe
Carbon = C
Copper Wire: It's simply copper that's been stretched into long strands.
Sorry I couldn't give you actual formulas.

Alloys do not have a chemical formula because they are a mixture of metals, and not a compound. This wire consists of the elements Au, Cu, Zn and Fe from your description.
