W70Cu30 Tungsten Copper Alloy Sheet Plate For Electrical Switches

W70Cu30 Tungsten Copper Alloy Sheet/ Plate Price Per Kg

Tungsten Copper Alloy Sheet/ Plate has a wide range of applications. It is mainly used to manufacture contacts of high-voltage electrical switches resistant to arc ablation, high-temperature components such as rocket nozzle throat lining and tail rudder. It is also used as electrodes for electrical machining, as the contact and protective ring of high-voltage and ultra-hydraulic switches and circuit breakers.
high-temperature molds and other occasions requiring conductivity and high-temperature use. it is widely used in military high-temperature resistant materials, electrical alloys for high-voltage switches, EDM electrodes and Microelectronic Materials. As parts and components.
Tungsten copper is refined from fine tungsten and copper powder by first-class infiltration sintering process. It can withstand nearly 2000 ℃ high temperature and high stress. It has high melting point, high hardness, anti burning loss and good anti adhesion. The surface finish of electric corrosion products is high, the precision is very high and the loss is low.

Tungsten Copper Alloy Sheet/ Plate combines the advantages of metal tungsten and copper. Among them, tungsten has high melting point (tungsten melting point is 3410 ℃, copper melting point is 1080 ℃) and high density (tungsten density is 19.25g/cm, copper density is 8.92/cm3); Copper has excellent electrical and thermal conductivity, tungsten copper alloy (composition generally ranges from wcu7 to wcu50) has uniform microstructure, high temperature resistance, high strength, arc ablation resistance and high density; With moderate conductivity and thermal conductivity.

Military high temperature resistant materials

W70Cu30 Tungsten Copper Alloy Sheet/ Plate Price Per Kg is used as nozzle, gas rudder, air rudder and nose cone of missile and rocket engine in aerospace. The main requirements are high temperature resistance (3000K ~ 5000K) and high temperature airflow scouring resistance. It mainly uses the sweating refrigeration effect formed by copper volatilization at high temperature (copper melting point 1083 ℃) to reduce the surface temperature of tungsten copper and ensure its use under extreme high temperature conditions.

1. Resistance welding electrode: it combines the advantages of tungsten and copper, high temperature resistance, arc erosion resistance, high strength, large specific gravity, good conductivity and thermal conductivity, easy to cut, and has the characteristics of sweating cooling. Due to the high hardness, high melting point and anti adhesion of tungsten, it is often used as projection welding and butt welding electrode with certain wear resistance and high temperature resistance.

2. Electric spark electrode: when the mold made of tungsten steel and high temperature resistant superhard alloy needs electric corrosion, the loss of ordinary electrode is large and the speed is slow. Tungsten copper has high electric corrosion rate and low loss rate,

Precise electrode shape and excellent machining performance can ensure the accuracy of the machined parts to be greatly improved.

3. High voltage discharge tube electrode: when the high voltage vacuum discharge tube is working, the temperature of the contact material will rise by thousands of degrees Celsius in a few tenths of a second. The high ablation resistance, high toughness, good conductivity and thermal conductivity of tungsten copper provide necessary conditions for the stable operation of discharge tube.

4. Electronic packaging material: it not only has the low expansion characteristics of tungsten, but also has the high thermal conductivity of copper. Its thermal expansion coefficient and conductivity can be changed by adjusting the composition of the material.
