Tungsten copper alloy combines the advantages of tungsten and copper, 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
The powder particle size and uniformity of tungsten powder and copper powder will affect the sintering effect of tungsten-copper alloy electrode to a certain extent. The reduction of powder particle size will make the comprehensive properties of materials such as density, hardness etc.
The morphological distribution of the tungsten-copper powder sintered material is uniformly distributed on the copper substrate with tungsten as a skeleton. Due to the high melting point and high hardness of tungsten W, the ultimate tensile strength of tungsten at 1000 ° C is still 50kgf / mm2
The tungsten copper powder sintered material is distributed in the form of tungsten as the skeleton evenly on the copper matrix. Due to the high melting point and high hardness of tungsten W, tungsten at 1000 ℃, its ultimate tensile strength is still 50kgf / mm2, higher than the strength of low-carb
