Copper chromium Cu-Cr alloys are important contact materials for vacuum interrupters. These alloys find wide use in high voltage applications because of their high voltage stress withstanding capabilities. They are also utilized in applications where there is a need for high strength and high thermal conductivity materials.
Owing to some of the properties mentioned above it is not that much easy to manufacture high-quality copper chromium Cu-Cr electrical contacts. A range of production processes is adopted for manufacturing these Cu-Cr electrical contacts. But mostly powder metallurgical processes are used. Most widely used procedure is mixing chromium with copper powder, compacting the mixture, sintering the green shape below the melting point of the Cu to produce blank for contact pieces. Another method can be varied as the skeleton of Cr is sintered and Cu is infiltrated. Cu in liquid phase produces an extremely strong bond between both the constituents.
Modison is one such company that offers copper chromium Cu-Cr electrical contact products. Supported by highly experienced professionals, the company is providing an excellent range of chromium copper discs.
