A copper-zinc alloy containing up to 40% zinc and some smaller amounts of other metals.
Up to 39% zinc - cold working alloys, soft and ductile

39% - 45% zinc - hot working alloys

above 45% - material becomes brittle.

Tin improves corrosion resistance.

Manganese is added for the deoxidization producing sounder castings and for improving tensile strength.

Aluminium increases tensile strength and corrosion resistance.

Nickel increases corrosion and erosion resistance.
