CuNi2Be (CW110C) vs CuZn36Pb2As
Side-by-side chemical composition and mechanical property comparison.
Overview
CuNi2Be (CW110C)
CW110C
Nickel-beryllium copper alloy, precipitation hardened. Higher strength than CuBe2 (CW101C) with better thermal conductivity. Age-hardened: Rm 690–850 MPa, Rp0.2 550–750 MPa, HB 200–280. Electrical conductivity ~50–60% IACS. Non-sparking. UNS C17510, EN CW110C. Applications: plastic injection mold inserts (core pins), resistance welding electrodes (for coated steel), springs, connectors, non-sparking tools, blow mold inserts.
CuZn36Pb2As
2.0372
Dezincification-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.
