CUZN30 : yellow brass
CUZN30 brass, also known as C26000, is an alloy of copper and zinc. Its copper content is 70% copper and 30% zinc. This yellow brass has the highest ductility of all yellow brass. It is very easily polished, nickel-plated or chromium-plated and is therefore widely used. It is mostly cold-formed.
