EN CW106C Chromium Zirconium Copper Alloys Bars For Rod Extensions

Chromium Zirconium Copper RWMA Class 2 Round Rods For Pencil-type

Introduction:

A copper chromium zirconium alloy CuCr1Zr conforming to RWMA Class 2 which is used mainly for resistance welding application but also other applications which require high electrical conductivity properties with a degree of wear resistance and a higher strength than pure copper.The alloy can also be specified to BS 2872/2874 CC102, EN 12165/12420 and Din 17673/17678-1 W Nr 2.1293.

Typical Uses:

A high copper alloy with extremely good electrical and heat conductivity that is strengthened by heat treatment.

Electrical

The main applications are for electrical connectors,switch gear and circuit breakers which require higher mechanical properties.It is also used in generators for commutor bars and end rings for electric motors.

Mechanical/Electrical

Used for welding wheels,spotwelding electrodes.seam welding wheels and tips.Electrode holders and arms; oxygen jet tips. Moulds inserts for non ferrous casting moulds.

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.
