Copper Chrome Zirconium
Copper Chrome Zirconium 5182 A2/2 CuCr1Zr – CC102
CC102/CW106C is a high copper alloy containing a small amount of chromium and zirconium that improves mechanical performance. Copper on its own has outstanding electrical and heat transfer properties but is soft and ductile. However, the small additions of these elements followed by a suitable heat treatment significantly increase strength while retaining high conductivity values.
This high-performance alloy has traditionally been used for a wide range of electrical and thermal conductors requiring greater strength than copper. This includes:
- Resistance welding equipment
- Switchgear components
- Circuit breakers part
- Rotating electrical machinery
- Current-carrying arms and shafts
- Switch contacts
- Heat sinks
- MIG welding contact tubes
- Soldering iron tips
Its high electrical and thermal conductivity, high strength levels and retention of mechanical properties at elevated temperatures (up to 525 °C) provide designers with low wear, long life and efficient performance. This ensures maximum retention of mechanical properties under practical working conditions.
- Very high electrical conductivity
- Good mechanical strength and toughness
- Very good thermal conductivity
- Resistance to softening up to 525°C
The main applications for CC102/ CuCrZr are for resistance welding shafts, electrodes, electrode holders, seam welding wheels and flash or butt welding dies all of which must have a high electrical conductivity to conduct the heat away from the weld and be strong enough to withstand the mechanical pressure required for welding. Copper chromium zirconium is also used for switchgear components, circuit breaker parts, rotating electrical machinery, electrical and thermal conductors where greater strength copper is required.
