Brass is essentially copper alloyed with zinc. It is strong but easy to form, stamp or draw which make it a common choice for a broad spectrum of applications. By varying the amount of zinc content it is possible to achieve a variety of characteristics including different levels of corrosion resistance, ductility and suitability for machining.

A higher zinc percentage increases the cold working strength whilst a higher percentage of copper yields greater ductility.

Its wide range of uses include automotive, naval, chemical, plumbing/heating and electronics industries. It’s acoustic properties combined with its workability also make brass the main choice of metal for the production of musical instruments.
