Copper Tungsten material produced by Powder Metallurgy wherein sintered skeleton of Tungsten is impregnated with Copper. The erosion pattern of this material is far superior to materials produced by other production techniques. This material maintains quite regular shape under extreme arcing conditions and has only uniform roughening effect without cracks and burn-off droplets.The Tungsten skeleton is protected by impregnated Copper as it provides evaporative cooling effect in extreme arcing conditions, thereby protecting and limiting the temperature rise of the skeleton and preventing disintegration.

We offer complete range of current carrying Main Contacts, manufactured as per customer’s drawings & specifications in CopperOFC, Copper Chromium, Copper Chromium Zirconium, Silver Bronze, Silver bearing Copper, CuZr etc.Plant is well equipped with CNC Turning and Machining Centers having full fledged in-house facility for full selective silver plating up to 100µm thickness. Silver plating can also be done selectively only on functional area as per customers requirement. All facilities under one roof helps in quick delivery of parts ready-to-assemble on the breaker pole.

The silver and tungsten composite group combines the high thermal and electrical conductivity of silver with the high erosion resistance of the high melting tungsten. These materials are also characterized by their high strength and their resistance to welding or sticking. They are principally made by infiltration and the nominal silver content varies from 20-50%. By increasing the amount of tungsten, the hardness and welding is reduced. This composite group of alloys is specially preferred for use in air.

Silver tin Oxide (AgSnO2) based contacts since their introduction are looked upon as potential replacement for AgCdO. The AgSnO2 contacts have seen continued improvisation, with respect to their applicability and performance, by enhancement in their fine microstructure.AgSnO2 based contacts are increasingly dominating the market for medium and high current contact relays because of their low arc erosion. Besides the base oxide SnO2 embedded in the Ag matrix, these materials may or may- not contain additives like Bi2O3, CuO, In2O3, WO3 and MoO3 in a combination of varying amounts not exceeding 2%. The AgSnO2 based contacts are manufactured by powder metallurgy (powder blending, compaction and sintering) followed by extrusion drawing rolling to the final dimensions.

Silver Cadmium Oxide Contacts in diverse forms manufactured by Internal Oxidation as well as Powder Metallurgy to meet customer’s specific requirement. These contact materials have high resistance to contact welding and arc erosion with low contact resistance.

Contact surface layer and backing metal are bonded metallurgically. This ensures the electrical and mechanical properties of CLADCON are as good as solid contacts. Electrolytic Copper provides better thermal and electrical conductivity than silver alloy and copper shank in CLADCON ensures longer life.With increasing silver prices, lower silver content of CLADCON allows choice of larger contact than with solid silver contact to get better performance.
