Tri-metal Contact has contact surface materials as Silver, Fine Silver, AgNi, AgInSnO2, AgCu, AgZnO, AgCdO, etc. Its base material as CuNi, Fe, FAg/Cu/Fe, AgNi/Cu/Fe, AgSnO2/Cu/Fe, AgCdO/Cu/Fe, etc.
The characteristics as follows:
1. Tri-metal contact has a contact surface as Fe material, with small convexesto 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 tight welding, and may increase electricity resistance in too loose 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.
Tri-metal Contact may select different silver alloy metal by different electricity currency in appliance. It is available for contact bridge conjunction by electricity pulse welding. It is used widely for contact parts making and bi metal bridge, such as relay, mini-switch, thermal controller, button and circuit breaker.
