Typically copper, but it is much harder than copper.
Gold, definitely. How about fixing this question as to what type of "brass" There is Yellow brass 60% Copper 40% Zinc and the more common red brass 85% copper and 15% Zinc then there is Muntz metal and Bronze thus BRASS = COPPER as there is NO gold content in "Brass"
One common alloy used to make imitation gold is brass, which is a combination of copper and zinc. Another alloy used is bronze, made from copper and tin. These alloys can mimic the appearance of gold at a lower cost.
