CuNi2Be (CW110C)
CW110CNickel-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.

CuZn37
2.0321Lead-free alpha/alpha+beta brass (63% Cu, 37% Zn). Compromise between cold formability (CuZn35) and hot formability (CuZn40). The most widely used unleaded brass. Used for cartridge cases, radiator cores, lamp components, plumbing fixtures, and decorative hardware.
CuZn36Pb3
CW603NFree-cutting leaded brass — the benchmark for non-ferrous machinability (rated 100%). Lead particles act as chip breakers for excellent surface finish. Used for screw machine parts, fittings, valves, watch components, precision mechanics, and electrical connectors. Old DIN number 2.0375.
CuSn6
CW452KPhosphor bronze with 6% tin — better cold formability than CuSn8 at slightly lower strength. Excellent spring properties and fatigue resistance. Used for electrical connectors, spring contacts, switch parts, bellows, bourdon tubes, and precision springs.
