UNS.C19150 Leaded Nickel Copper

UNS.C19150 Leaded Nickel Copper C19150 is unique precipitation hardening alloys containing copper, lead, nickel and phosphorus. The nickel and phosphorus in the alloy combine to form nickel phosphate, which dissolves in the copper on heating to a suitable temperature, and can be retained by quenching. Subsequent aging will precipitate the nickel phosphate from solid solution in a highly dispersed manner thereby creating a remarkable hardening and strengthening effect with excellent stress relaxation properties. Subsequent cold working increases the strength still further.

Since the lead and nickel phosphate are not in solid solution when the alloys are in the precipitation hardened condition, the electrical conductivities are comparatively high. When suitably heat treated, one can expect a conductivity of about 55% IACS. The lead content also imparts good machinability to both alloys.

The properties of UNS.C19150 alloys make it an ideal material for machined, formed or cold headed electrical contacts, connector pins and sockets, particularly for slotted cylindrical contacts for coaxial and circular connectors.
