<P> Brass is a metallic alloy that is made of copper and zinc . The proportions of zinc and copper can vary to create different types of brass alloys with varying mechanical and electrical properties . It is a substitutional alloy : atoms of the two constituents may replace each other within the same crystal structure . </P>
