Kova
Kova® - the 'beryllium-free' alloy made of copper, nickel, silicon and chromium (CuNiSiCr).
Kova is a high-strength, beryllium-free precipitation hardening alloy with medium-high electrical and thermal conductivity.
Kova is the perfect replacement for harmful beryllium copper alloys.
Benefits:
- Easy to machine and form
- Extended use due to hardness
- High strength with moderate thermal and electrical conductivity
- Easy disposal
Applications:
- Adaptors
- Shanks
- Projection welding electrodes
- Weld wheels
