Longsun Company is a leading manufacturer of electrical contact materials and contact product. It was established in 1986 and registered capital is RMB 290 million, owning ISO9001:2015,ISO14001:2015,OHS45001 certification.
Powder Melltallurgy Silver Tungsten Carbide Silver alloys Contact Tips widely used in contactor, medium voltage switch
1. Product name: Silver Tungsten Carbide High performance silver Alloy contact for Medium /High voltage Vaccum switch, contactor,MCB, AC&DC Contactor
2. Materials: AgWC Silver Tungsten Carbide AgWC40 AgWC50 AgWC60 
3. general description
AgWC material has a good performance in resistance to contact welding and installation, low contact resistance and high arc erosion resistance.
AgWC is very hard and sufficient mechanical strength, druing arcing a protective gas layer of CO is formed which limits the reaction of oxygen on the contact surface and therefore the formation of metal oxides.
4. application Scope
Widely applied in various kinds of universal type breaker, MCCB (molded case circuit breaker,heavy load of AC&DC contactor and other switch electrical appliances, etc.

6. product feature
1, Tri-metal contact has a contact surface as Fe material ,with small convexes to increase welding. It helps the welding stability of contact with bi-metal sheet and stainless steel sheet base materials etc.
2, Welding position is bonded by melting metals. Its electrical stability is much better than riveting contact with its perfect image and position ,If riveting ,may commonly distort bi metal in too lose welding .Later it influences temperature meter with data deviation .
3, By comparison with Welding Contact ,it has short heat time and clean environment .It is available for mini part producing ,especially for mini system .
7. Packing and Delivery
Inside:Vaccum plastic bag
Outside:Carton
According to customers' request
Delivery: within 15 days
