Description
CZ132, a machining brass engineered to resist dezincification, excels in applications involving warm, acidic waters. It successfully meets the dezincification test outlined in ISO 6509 standards. For the production of hot-stamped components with improved hot-working properties, it’s advisable to consider C35330. If dezincification resistance is required, a heat treatment after hot working may be necessary.
