CuZn36Pb2As
2.0372Dezincification-resistant (DZR) leaded brass with arsenic addition (0.02–0.15% As). Specifically developed for potable water applications where standard brasses suffer dezincification attack. Good machinability (70% of CW614N). Compliant with WRAS (UK), ACS (France), 4MS (EU) approvals for drinking water. Used for water meter bodies, valves, fittings and plumbing components. The As addition inhibits selective zinc leaching in aggressive water conditions.
