CuNi1Pb1P-UNS.C19160 Leaded Nickel Copper

CuNi1Pb1P-UNS.C19160 Leaded Nickel Copper C19160 and C19140 are 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.

C19160 is nominally composed of 97.8% copper, 1.0% lead, 1.0% nickel and 0.2% phosphorus, while C19140 is nominally composed of 98.3% copper, 0.5% lead, 1.0% nickel and 0.2% phosphorus. They are noted for their high corrosion resistance, high tensile and yield strengths, high electrical conductivity, machinability and resistance to stress relaxation.

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.
