Properties:

Alloy for metallic materials used for products in contact with drinking water.

Application:

CuZn38As materials can be used for drinking water products, the high copper content makes the  alloy an excellent material for stamping with a good dezincification values. The reduced lead content makes the alloy compliant with requirement for drinking water. It can be used for water qualities that require dezincification resistant material.
