High Density Tungsten-Based Heavy Alloys Tungsten Nickel Copper Alloy Rod W-Ni-Cu
1. Introduction Of Tungsten-Based Heavy Alloy W-Ni-Cu alloy rod:
Tungsten-nickel-copper alloy refers to an important class of tungsten-based heavy alloys, which are alloys composed of nickel and copper added to tungsten, and alloys with other metal elements added on this basis. The ratio of nickel and copper added is generally 3:2. This kind of alloy is non-ferromagnetic and has relatively good electrical and thermal conductivity. It is often used in occasions with special requirements, such as gyroscope rotors and other parts of devices and instruments that require to work under the action of a magnetic field; electrical contacts of high-voltage electrical switches And some electrodes for electrical processing.
