Superior brazing and weldability
The excellent conductivity of copper can be maintained while raising the softening temperature dramatically and increasing strength with the small addition of zirconium. Zirconium copper can be brazed in a reducing environment without dimension changes or internal porosity and offers immunity to hydrogen embrittlement.
Zirconium copper can be easily welded and is well suited for electron beam welding.
Advantages of zirconium copper include:
- Higher softening temperature
- Increased strength
- Improved conductivity
- Fine grain size
- Lead frames
- Continuous casting moulds
- Spot welding electrodes
- Wheels and adaptor shanks
- MIG/MAG welding contact tips
- Commutator bars
- Radial stalks for generator rotors
Luvata offers a full range of zirconium copper products including:
||Cr 0,8%, Zr 0,15%
We also supply spot welding electrodes.
