SILVER-TUNGSTEN (CARBIDE) MATERIALS, COPPER-TUNGSTEN
Properties
- Lowest contact erosion rate based on high-melting-point metal (e.g. tungsten) and carbides
- Excellent anti-welding properties in conjunction with silver-graphite
Our sintered electrical contact facings are produced using either the press-sinter-infiltration (PSI) or press-sinter-repress (PSR) method. We supply them as contact facings that are designed with a solderable underlayer in the form of an infiltration excess (PSI) or a discreet underlayer (PSR), depending on the process. On request, they are also available with an additional layer of hard solder. Our sintered contacts are ideal for all types of circuit breakers and protective switches (MCCB, ACB, MCB, RCCB, AFCI, GFCI).
