Comparison of Production Technology of Tungsten Copper Alloy
Conventional tungsten copper alloy is generally prepared by copper infiltration and liquid sintering method, but because of tungsten copper incompatibility of its sintering performance is poor, it is difficult to achieve complete sintering densification, it is difficult to form a uniform microstruct ...

Why should the electrical alloy contact be inlaid with a piece of pure silver block or silver based alloy block?
The contact surface of the contact will oxidize when contacted with the atmosphere. If the copper is oxidized, the surface will produce copper oxide or cuprous oxide film. The conductivity of copper oxide film is very poor, and its resistivity is more than 1016 times larger than that of pure copper. ...

Classification, construction and application of electrical contacts
(1) classification of electrical contacts Electrical contacts can be divided into the following three types according to their contact modes 1) fixed contact. An electrical contact that cannot be moved relative to a conductor connected by contact. Such as bus connections, electrical equipment, such ...
