The special alloy electric contact is a new kind of Electric Contact, which is very cheap and has a high property. The new materials can be widely applied into many kinds of electric circuit breaker, contact and other low volt electric apparatus. After continuing research and accumulating experience, the products’ quality could now meet the requirement of practical use of many electric apparatus.
To further meet customer requirements, we have developed a new kind of special alloy electric contact, which has a three-layer structure, thus the applied areas of special alloy electric contact could are expanded. The three-layer structure involves a surface layer of Ag alloy, a matrix layer of special alloy electric contact and an under-matrix layer of solder as welding materials. The compositions and producting methods of the three layers have independent intellectual rights. With the application of a special technique, the Ag alloy layer and special alloy layer is perfectly connected, thus the product cost is largely decreased, and also the antioxidant capacity of Ag as well as the long life span and high anti-welding properties are reserved. In the quality tests, the results prove that the new materials improve the quality and stability of many electric apparatus, and therefore have a promising future in many applications.
The three-layer structure could achieve different properties meeting the demands from customers through different compositions and thickness of Ag alloy. The composition can include all traditional ones and the thickness varying from several um to mm. Now with a mature production technology, advanced testing equipments and perfect production management, the company is now open for large amount of order and can deliver as scheduled.
