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 made 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℃, 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.
Since tungsten and copper are insoluble in each other, tungsten copper alloy has the low expansion, wear resistance, corrosion resistance of tungsten and the high electrical and thermal conductivity of copper, and is suitable for various mechanical processing. Tungsten copper alloy can be produced and processed according to user requirements. Tungsten copper alloy generally uses the process of powder metallurgy first powder making-mixing-pressing molding-sintering and dissolution.
Tungsten copper electrode-welding electrode
Tungsten copper alloy has high temperature resistance, arc ablation resistance, high specific gravity and high electrical and thermal conductivity and is easy to machine and is suitable for use in welding electrodes.
Tungsten copper alloy rod
Tungsten copper is a composite material made by static pressing, high temperature sintering and copper infiltration process using the excellent metal properties of high-purity tungsten powder and the plasticity and high conductivity of high-purity copper powder. It has 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 electronic packaging sheet
Tungsten copper electronic packaging material: It has both the low expansion characteristics of tungsten and the high thermal conductivity of copper. Its thermal expansion coefficient and electrical and thermal conductivity can be changed by adjusting the composition of the material, which provides convenience for the use of the material.
Tungsten copper tube
Tungsten copper alloy tubes are widely used in cemented carbide and refractory metals. Because tungsten copper alloy is easy to machine, the use of tungsten copper tubes plays a great role when the surface needs to be easy to cut and the inner diameter is small.
Tungsten copper alloy wire
Precautions for use:
1. Colloidal graphite cannot be placed on the surface of tungsten copper wire. When the temperature is above 1000 degrees, avoid putting tungsten copper wire together with iron, nickel and carbon. Tungsten copper wire must be placed in a dry place, and the relative humidity should not exceed 65% of the room temperature. Avoid placing it together with acidic or alkaline substances.
2. After cleaning the tungsten copper wire, it should be placed in a dry container to avoid direct contact with the air to prevent oxidation.
