Electrical Contact

The Electrical Contact is used in high power applications and to prevent the formation of corrosion products. The technical criteria of an electrical contact depend upon three kinds of parameters: physical properties of contact material (P), e.g., hardness, electrical resisitivity, melting point, chemical reactivity, melting point; design parameters of the switching device (D), e.g., contact force, opening & closing velocity, specific magnetic induction; and stress parameters of the service conditions (S), e.g., type of electrical load, ambient temperature, air pollution. A range of electrical contacts like rivet contacts, flaking contacts, flap powdered contacts, silver alloy contacts, copper compound contacts, iron compound contacts and flap internal oxidizing contacts are offered. All this electrical contact is available in material like Ag & AgNi (0.15), AgNi & AgFe, AgCd & AgCu, AgCdO, AgZnO, AgSn2In2O3, AgW & CuW, AgWC, Agc & CuW, AgC & CuC, silver, silver alloy compound slab, silver alloy, copper, and iron and electroplated silver plate.
