Information about brass
Brass band consists of a copper/zinc alloy: CuZn.
ILNOR can provide you with brass band alloys according to the DIN/EN standards.
The base of the alloy is copper with a tin component e.g. CuZn37 = 63% copper, 37% zinc (as well as small traces of other chemical elements).
The higher the copper component, the higher the price of the alloy on the metal markets.
