CW721R / CZ114 is a high tensile brass consisting of a duplex structure. Developed for more exacting applications where strength and corrosion resistance are required. Also referred to as a manganese bronze the CW721R / CZ114 has additions of aluminium, iron, tin and manganese that are added to the basic 60/40 brass matrix, creating a variety of properties to benefit the designer.

The aluminium and tin content gives the CW721R / CZ114 a brighter finish and is the main reason for the increase in corrosion resistance. The iron and manganese additions also improve the strength level, with the iron also acting a grain refiner. Some of the other benefits of the CW721R / CZ114 grade are a very good hot working capacity to allow for hot stamping and a good machinability rating.
