CW721R (CZ114) is a high tensile brass that is significantly stronger than the conventional free-machining brasses, equalling the strength of many steels whilst still retaining the benefits of copper alloys. The addition of manganese and tin in the material helps to greatly improve corrosion resistance, whilst sufficient lead is present for the machinability to be good.
CW721R is a non-sparking material and offers good corrosion resistance. It is a high strength alloy with excellent hot forming properties. Weldability is excellent when soldering or brazing.
CW721R is sometimes referred to as a Manganese Bronze or High Tensile Brass.
