CuCr1Zr Alloy/ UNS.C18150 Chromium Zirconium Copper Rods Length Could Be 3000mm

Product Normal Description:

UNS.C18510 chromium zirconium copper alloys is a high conductivity, high strength copper alloyed with chromium.

C18510 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. C18510 is heat treated to high strength, and requires no further heah treatment. It meets the requirements of RWMA (Resistance Welder Manufacturers Association) Group A, Class 2.

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.
