Our products Three Compound Contacts Features:
1-Trimetal Contacts can save costs 30%-65% than Solid Silver Contacts;
2-Very reliable mechanical strength for both sides composite materials,like Solid Contacts;
3-The silver layers on the head and foot are accurately distributed to ensure the contacts gap after riveted with stamped terminal;
4-Surface anti-oxidation protective film, can resist oxidation for a long time;
5-High dimensional accuracy ±0.01-0.02mm;
6-Strong corrosion resistance;
7-Good electrical conductivity.
Tri-metal Rivet Contacts are normally used as double sides contacts,mainly used in Relays, Micro Switches,Button Switches and Contactors,etc.Trimetal Material have Ag/Cu/Ag,AgNi/Cu/AgNi,AgCdO/Cu/AgCdO,AgZnO/Cu/AgZnO, AgSnO2/Cu/AgSnO2,AgSnO2In2O3/Cu/AgSnO2In2O3 and so on.Available with us is a range of Contact Rivets. Trimetal Electrical Contacts are manufactured with wire by cold heading process. This helps in making the shank soft for easy riveting and the head is work-hardened. The length of the shank can be varied but the diameter of Trimetal Contact Rivets is needed to be in right proportion to the size of head. This enables us to avoid wrinkles during cold forging operation. These economically priced Composite Contact Rivets can be manufactured in various dimensions. The limit to the dimension of Multi-layer Silver Contacts is due to the requisite ratio between head diameter to head thickness.
Nowadays, the commonly used contact elements on the market are small in size, but have very strict performance requirements. Most of the existing contact elements are made of pure silver and pure copper materials directly by manual riveting and automatic riveting, with low strength, low hardness, low welding resistance and arc burning resistance, and the materials involve a variety of precious metals Materials, most of the existing composite contact manufacturing equipment have complex structures and poor molding efficiency, which not only wastes raw materials, but also the molded composite contacts have low strength and hardness, unstable connection, high cost, and small application range,so the Trimetal Silver Contacts is the best choice to reduce costs and increase efficiency.
The Tri Metal Contact Rivets are contacts composed of two or three materials. Generally, the head is covered with silver (silver alloy), the base is copper, and the feet are also covered with a layer of silver (silver alloy). , This process is slowly becoming popular internationally and is a good cost-saving method; the spot welding type Three Compound Contacts are also a contact composed of two or three materials. The common one is a layer of silver (silver alloy ), the middle layer is copper, and the bottom layer is iron (or iron plated with nickel or Monel alloy).
