Cr-Cu, W-Cu Contacts - polema-rus

Currently, the most common material used in contact pairs in VACs are Cr-Cu composites. Contacts are subjected to the effects of short-circuit currents and fusing metals in various points of the surface due to the high density of the current in them; as a result, welding joints form in these zones.

Contact Carrier Materials - Electrical Contacts

Cu-ETP is less suitable for welding or for brazing in reducing atmosphere because of the oxygen content (danger of hydrogen embrittlement). ... Because of the always present thin oxide layer on its surface, nickel is not suitable as a contact material for switching contacts.

Preparation and Characterization Cu-Cr Contact Material ...

Cu-Cr contact material is used in medium voltage, high current vacuum interrupters. Vacuum interrupter is the heart of Vacuum Circuit breaker. Contact tips are usually made using powder metallurgical techniques in disk shape. These disks are machined to required dimensions and then hermitically sealed by vacuum brazing. The properties of the final contact tips are thus usually rarely studied.
