Brass is an expensive metal that is furthermore reasonably stable in value.
Brass is an alloy of copper and zinc. This alloy is sometimes also referred to by its formula CuZn. A thin sheet of brass may also be called latten. Another name used for brass is ormolu. This has to do with its colour: ormolu is brass that at first glance somewhat resembles gold. When brass is exposed to the air, it becomes darker and more brownish. An important characteristic of brass is that it is a relatively hard metal, meaning that it has been in wide use since prehistoric times.
Brass is an alloy of varying proportions of copper and zinc. Nowadays, nearly 90% of discarded brass is re-used – making brass, like lead, one of the more extensively recycled metals.
