Tungsten Copper Nickel Alloy

Tungsten Copper Nickel Alloy Gravity: General accounting for 16.5 ~ 18.75g/cucm;
Power: tensile strength of 700 ~ 1000MPa;

High proportion of tungsten copper-nickel alloy is a kind of matrix of tungsten (W content of 85 to 99 percent), and supplemented with Ni, Cu, Co, Mo, Cr and other elements of the alloy. The non-ferromagnetic alloy, relatively good thermal conductivity properties, often used in some special requirement, such as a gyroscope rotor, and other requirements to work in the magnetic field devices and instrumentation components, high-voltage electrical switch electrical contacts and some EDM electrodes used. Can also be used in full bloom radium containers counterweight and other requirements of high-density parts.

Tungsten Copper Alloy used in Military High Temperature Materials

Tungsten copper alloy used in aerospace missile, the rocket engine nozzle vane air rudder, nose cone, the main requirement is to require high temperature (3000K ~ 5000K), high temperature air scour capacity,
the main use of copper at high temperatures volatile refrigeration sweat formed (copper melting point 1083 ℃), tungsten copper lower surface temperature at high temperature to ensure the use of extreme conditions.

High-voltage Switch with Electrical Alloy

Tungsten copper alloy in high-voltage switchgear 128kV SF6 circuit breakers WCu / CuCr medium, and high-voltage vacuum load switch (12kV 40.5KV 1000A), surge arresters are widely used, high-voltage vacuum switches, small size, easy to maintain, using a wide range of energy in the wet, the use of flammable and corrosive environments. The main performance requirements arc erosion resistant, anti-welding, cut-off current, gas-less, low thermal electron emission capability. In addition to conventional macroeconomic performance requirements,

but also requires the porosity, microstructure properties, it should take a special process, the need to vacuum degassing, vacuum infiltration and other complex processes.

Tungsten copper and copper alloys

EDM carried out in the beginning than eternal room , copper or copper alloy is widely used as a processing electrode . Copper and copper alloys although expensive , easy to use , What, then copper and copper alloy electrodes because of impatience spark ablation electrode consuming large machining accuracy, occasionally need to stop the repeated processing. Many die along with the amount of difficult to machine precision, and data components of growth from time to time , as well as technology has become more sophisticated EDM , tungsten copper data as the cumulative amount of EDM electrodes . Currently, tungsten copper alloy can be used as resistance welding electrode ,

the electrode data EDM electrodes , plasma electrodes. In the EDM process, probation electrode data is processed pulses walks and minimal consumption of its own in addition to the erosion of the workpiece . Tungsten and copper data processing speed with fast , high- quality processing , data consumption is small electrode characteristics . Thus , work on finishing high speed machining of molds and hard data , such as a significant advantage . As EDM tungsten copper electrode request information both excellent thermal conductivity function , but also has good anti- corruption functions spark , and the data structure to be very average compact.
