Tungsten copper alloy 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.
Tungsten copper rod 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.
Tungsten-copper alloys are pseudo-alloys of refractory metals, so tungsten-copper alloys can only be produced by powder metallurgy. The manufacture of tungsten copper tube is a bigger challenge in production process.
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
Tungsten-copper alloy material has the advantages of both tungsten and copper. Tungsten is resistant to high temperature (greater than 3000 degrees) and is therefore resistant to burnout.
Like tungsten silver (WAg) contacts, tungsten copper (WCu) contacts are a typical tungsten contact. Since both tungsten silver and tungsten copper contacts are based on refractory metal tungsten, their physical and chemical properties, production methods and uses are basically similar.
The improvement of the performance of tungsten-copper alloy is a concern of modern manufacturers. The alloy is a uniformly mixed structure of two-phase monomers of tungsten and copper. It is neither miscible nor intermetallic. It is a typical pseudo alloy.
Tungsten-copper alloys can be used in many electrical appliances due to their high melting point, high conductivity, and good ablative resistance.
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
