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.

The CW602N / CZ132 dezincification resistant brass (DZR Brass) is essentially a leaded arsenical brass with a duplex structure. As its name suggests it was originally developed to provide good resistance to dezincification type corrosion which is experienced by normal hot working brasses.
As well as the improved dezincification / corrosion resistance the CW602N / CZ132 also offers good strength levels, is readily machined and easily hot forged. Its primary usage over the years has been for water fittings that are produced by hot stamping and machining.
