Metal Alloy W-Cu Alloys Bar Custom Size Tungsten Copper Alloy Rod

About Metal Alloy W-Cu Alloys Bar Custom Size Tungsten Copper Alloy Rod:

Tungsten copper rod is an alloy composed of tungsten and copper. The copper content of commonly used alloys is 10% to 50%. The alloy is prepared by powder metallurgy and has good electrical and thermal conductivity, good high temperature strength and certain plasticity. At very high temperatures, such as above 3000 °C, the copper in the alloy is liquefied and evaporated, absorbing a large amount of heat and reducing the surface temperature of the material. Therefore, this type of material is also called metal sweating material.

Tungsten copper is a composite material refined by the process of static pressing, high temperature sintering, and copper infiltration by utilizing the excellent metal properties of high-purity tungsten powder and the plasticity and high conductivity of high-purity copper powder. Good arc breaking performance, good electrical and thermal conductivity, small thermal expansion, no softening at high temperature, high strength, high density, and high hardness.

Tungsten-copper alloy has a wide range of uses, mainly used to manufacture contacts of high-voltage electrical switches that are resistant to arc ablation, rocket nozzle throat linings, rudders and other high-temperature components, as well as electrodes for electrical processing, high-temperature molds and other high-temperature components. Occasions that require electrical and thermal conductivity and high temperature use.

Resistance welding electrodes
Resistance welding electrode (select tungsten copper WD10080): It combines the advantages of tungsten and copper, high temperature resistance, arc ablation resistance, high strength, large specific gravity, good electrical and thermal conductivity, easy to cut, and has the characteristics of sweating and cooling. Due to the high hardness, high melting point and anti-adhesion characteristics of tungsten, it is often used as projection welding and butt welding electrodes with certain wear resistance and high temperature resistance.

Spark electrode
EDM electrode (choose tungsten copper WD10070, WD10075, discharge tungsten steel should choose WD10080): When the mold made of tungsten steel and high temperature superhard alloy needs to be eroded, the loss of ordinary electrodes is large and the speed is slow. Corrosion speed, low loss rate, precise electrode shape, and excellent processing performance can ensure that the accuracy of the workpiece is greatly improved.

High Voltage Discharge Tube Electrodes
High-voltage discharge tube electrode (select WD10070): When the high-voltage vacuum discharge tube is working, the temperature of the contact material will increase by several thousand degrees Celsius within a few tenths of a second. , The thermal conductivity provides necessary conditions for the stable operation of the discharge tube.
