Description

CZ132 (CuZn36Pb2As) is a dezincification resistant (DZR) brass containing small amounts of lead and arsenic. It was originally developed to provide good resistance to dezincification type corrosion which is experienced by normal hot working brasses. In addition to good corrosion resistance, CZ132 (CuZn36Pb2As) offers good strength levels and is readily machined and hot forged. It is ideal for water fittings that are produced by hot stamping and machining.
