CZ132 Brass – Know the Properties, Benefits & Applications

CZ132 Brass, which is also known as CW602N DZR (dezincification resistant) brass represents brass that has minute amounts of lead and arsenic and comes with a duplex structure.

This brass alloy has been made ideally to provide high resistance levels to dezincification corrosion – which is a feature easy to find in hot working brasses.
