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.
Ag/Cu/Ag Tri-metal Contact Rivets are manufactured either by bonding of multiple wire segments or by cutting and forming from a suitable tri-metal strip. When using the latter method it is also possible to use different Tri-metal Rivet Contacts materials for the contact layers if different load conditions have to be controlled.Trimetal Contact Rivets are more advanced compared to Bi-Metal Contacts. To reduce the production cost and to fight against the threat for increasing silver prices, Electrical Trimetal Rivet Contacts are solving the purpose. We have the capability to manufacture Trimetal Contact Rivets with silver alloy layer of any composition bonded with ETP Copper on both sides.
Trimetal Moving Contacts, comprising a copper base layer and a silver alloy layer, the top of the copper base layer is provided with a cylindrical foot, the silver alloy layer includes a top silver alloy layer and a bottom silver alloy layer, the top silver alloy layer It is a ring structure, the inner ring part is sleeved on the cylindrical foot; the bottom silver alloy layer is fixed on the bottom of the copper base layer; the top and bottom are made of silver alloy layer materials.So the Double Side Contacts are made by special cold-heading machines.
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).
The new Ag/Cu/Ag Trimetal Contacts include a matrix and a composite layer. The matrix is composed of a head and a foot. The head and the foot are both cylindrical, and the diameter of the head is larger than the diameter of the foot. The composite layer includes a head composite layer and a foot composite layer, the head composite layer is composited on the upper surface of the head, and the foot composite layer is composited with the lower surface of the foot; the matrix is made of pure copper material , The composite silver layer is made of silver alloy material, and the silver alloy is composed of fine-grained silver; the beneficial effects of the utility model: the utility model relates to providing Trimetal Electrical Rivets using pure copper and silver alloy, The composite molding of pure copper and fine-grained silver materials is used, with low production cost, high material strength, high welding resistance and arc burn resistance, high electrical conductivity, and low contact resistance. Three Compound Rivets are suitable for low-voltage electrical appliances with operating currents below 10A. The Electric Double Metal Contact Rivet that can replace pure silver materials are applied to many occasions.
