Description
CW602N, a machining brass designed to resist dezincification, excels in applications involving warm, acidic waters. It successfully meets the dezincification test criteria outlined in ISO 6509. When producing hot-stamped components, it’s advisable to opt for C35330 due to its superior hot-working properties. To ensure dezincification resistance, consider a heat treatment after hot working when necessary.
