BRASS
It is an alloy of copper and zinc; it is much stronger, flexible and most adequate to be used in thin sheets. In ancient times any type of copper alloy, especially that made with tin, was called “brass”. The modern alloy came in use in the XVI century.
The malleability of brass varies according to the composition, temperature and the presence of external metals. All types of brass become fragile when heated at the temperature of the melting point.
