Tungsten Copper Inlaid Electrode Copper Tungsten Alloy Electrode Copper Tungsten Composite Electrode
1. Information Of Tungsten Copper electrode:
Tungsten copper electrode is a composite material composed of tungsten and copper. Tungsten copper alloy electrode combines the good properties of tungsten and copper, high temperature resistance, arc ablation resistance, high strength, high specific gravity, good electrical and thermal conductivity, and easy processing , and its functions such as sweating, and tungsten high hardness, high melting point, anti-adhesion characteristics, often used to make a certain wear resistance, high and low temperature resistance welding, butt welding electrodes.
2. Classification Of Tungsten Copper electrode:
Tungsten Copper Composite Electrode:
The tungsten-copper composite electrode eliminates the problems of pores and cracks in the welding composite used in the past. An electrode made of tungsten, copper, and iron is called a tungsten-copper-iron composite electrode. It has high bonding strength and good electrical conductivity. It combines the advantages of tungsten and copper. It has high temperature resistance, arc ablation resistance, high hardness, high melting point, high strength, High specific gravity, high electrical conductivity, high thermal conductivity, easy cutting, anti-adhesion, and has the characteristics of sweating and cooling.
Tungsten copper inlaid electrode:
The performance of tungsten copper inlaid electrode is guaranteed by the combination of heat treatment and cold processing. It can obtain the best mechanical properties and physical properties. It has the advantages of good uprightness, no bending of thin slices, and high finish when used as an electric spark electrode. It is used in high Precision and mirror surface mold discharge machining, or as large molds and fixtures for projection welding machines, molds for stainless steel and heat-resistant steel, or inlay electrodes. In addition, tungsten copper can be used as general-purpose resistance welding electrodes, mainly as electrodes for spot welding or seam welding of low-carbon steel and coated steel plates, and can also be used as electrode holders, shafts and gasket materials for welding low-carbon steel.
