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 tips are produced using either the press-sinter-infiltration (PSI) or press-sinter-repress (PSR) method. We supply them as contact facings designed with a solderable underlayer in the form of an infiltration excess (PSI) or a discreet underlayer (PSR), depending on the process. Upon request, they can be supplied with an additional layer of solder. Our sintered contacts are ideal for all types of circuit breakers and protective switches (MCCB, ACB, MCB, RCCB, AFCI, GFCI).
