Characteristics of tungsten-copper?

Release time:


1.Resistance welding electrode: It combines the advantages of tungsten and copper, featuring high temperature resistance, arc erosion resistance, high strength, high specific gravity, good electrical and thermal conductivity, easy machining, and sweating cooling characteristics. Due to its high hardness, high melting point, and anti-adhesion properties of tungsten, it is often used as a wear-resistant and high-temperature resistant projection welding and butt welding electrode.

2.Electric spark electrode: When molds made of tungsten steel or high-temperature resistant superhard alloy require electrical erosion, ordinary electrodes have high wear rates and slow processing speeds. However, tungsten-copper electrodes offer high electrical erosion rates, low wear rates, precise electrode shapes, and excellent machining performance, greatly improving the accuracy of the processed parts.

3.High-voltage discharge tube electrode: During the operation of a high-voltage vacuum discharge tube, the contact material can reach temperatures of several thousand degrees Celsius within a few hundredths of a second. The high erosion resistance, high toughness, and good electrical and thermal conductivity of tungsten-copper provide the necessary conditions for stable operation of the discharge tube.

4.Electronic packaging material: It combines the low thermal expansion characteristics of tungsten with the high thermal conductivity of copper. Its thermal expansion coefficient, electrical conductivity, and thermal conductivity can be adjusted by modifying the material composition.
