BRASSWIND

Brass is an alloy consisting of copper (Cu) and zink (Zn), occasionally with a small amount of other metals. The mixing ratio between copper and zink varies depending of the use of the alloy. The brass used in wind instruments is called Yellow Brass and typically consists of 72% copper and 28% zink. Sometimes the mixing ratio is 85/15 and called Gold Brass, while the 90/10 ratio is called Red Brass.
