UNS.C18150 Copper Rods Diameters 1mm~8mm For Circuit Breaker Switches
Features:
C18150 has good thermal and electrical conductivity. More than 400 varieties of these copper alloys are available, but C18150 is highly preferred since it has high strength and wear resistance at elevated temperatures. C18150 is used extensively for cap-style resistance welding electrodes. It can provide less sticking and resist deformation for much longer than its copper-chrome counterpart in some specific situations.
The chemical composition of C18150 is 1% chromium, 98.85% copper, and 0.15% zirconium. The addition of Zirconium to chromium copper improves creep resistance at high operating temperatures and reduces sticking of electrodes to the work during spot welding of galvanized or coated materials. The physical copper properties of C18150 include a density of 8.89 grams per cubic centimeter.

CUBERYLLIUM®-815 is a high conductivity, high strength copper alloyed with chromium. C18150 is heat treatable, and resists softening in service up to temperatures of 500°C. It is used for spot and seam welding electrodes, plastic mould components and other applications requiring excellent electrical and thermal conductivity and high strength and wear resistance at high temperatures.
C18150 when used for spot and seam welding electrodes can provide less sticking and resists deformation longer than copper-chromium (C18200) in some specific situations. C18150 can be used instead of C18200 in any structural or current carrying application.
C18150 can be used to spot weld: cold rolled steel, hot rolled steel, nickel plated steel, zinc and zinc-aluminium coated steel (galvanised and zincalume), nickel alloys, Monel, nickel silver, stainless steel.
