Product Description

C18200 Chromium Copper bars and rods for electrode material as per RWMA CLASS 2



Product Description

CuCr1 – UNS.C18200 Chromium Copper is a heat treatable copper alloy offering good electrical conductivity, resistance to softening at elevated temperatures and good strength and hardness. This combination of properties makes C18200 one of the preferred resistance welding electrode materials for a variety of applications. Nominally composed of 99.1% copper and 0.9% chromium, this heat treatable alloy can be brought to its softest condition by annealing it at 1000°C (1850°F) for one-half hour at temperature, then rapidly quenching it in water. In this annealed condition, the alloy is ductile and easily formed, and has an electrical conductivity of about 40% IACS.



Typical Application for UNS.C18200 Chromium Copper Alloys:



Electrical Industry: Cable, Connector, Thermal Conductors, Switch Gears, Electrical Connector, Circuit Breaker Parts, Switch Contacts, Electric Motor and Generator Components, Parts for electronic Devices



Consumer: Rod Extensions, Pencil-type, Light Soldering Guns, Tips



Industrial: Resistance Welding Machine Electrodes, Resistance Welding Equipment, Plastic Mold Components, Flash Welding Electrodes, Electrode Holder Jaws, Seam Welding Wheels, Wear Plates on Heavy Equipment, Heat Sinks, Spot Welding Tips, Molds
