Parts made of copper and copper-chromium alloys transmit electrical current with
extremely low resistance. Copper is also very resistant to corrosions, whether it is
above or below the waterline. The hardness, conductivity, and not least the cost
can be varied by using different alloys.
Areas of application
Designs produced as gravity die copper castings can be found wherever electrical
current flows. As contact holders, short circuit rings, grounding contacts,
contact tabs, high-voltage switch components, electrode arms, and much
more, they are used in a wide range of applications:
- in electrical systems
- in power supplies
- in converters
- in transformers
- in railway applications and overhead lines
- for welding electrodes
- Cu-C is highly conductive and offers a wide range of applications. When silver-plated it has even higher conductivity, particularly at contact surfaces.
- CuCr1 is a chromium alloyed copper material that is particularly hard and strong. It nevertheless has good electrical conductivity.
