Brass is an alloy of copper and zinc and the ratio of the mix can be varied to produce the desired properties, which might be electrical, mechanical or chemical in nature. This amazing alloy was widely used in the making of antique furniture and here are a few surprising facts about brass that you probably didn’t know.
