Well Sale Low Price Copper Tungsten Tube Products Tungsten Copper Pipe
Copper Tungsten Tube Tungsten-copper alloy contains 6-50% (weight ratio) of copper, and has the advantages of tungsten and copper: high temperature resistance, arc ablation resistance, high strength, high specific gravity, good electrical and thermal conductivity, small thermal expansion, easy cutting and processing, and With the characteristics of sweating and cooling, it is widely used in machinery, electric power, electronics, metallurgy, aerospace and other industries.
Copper Tungsten Tube are widely used in:
Arc contacts and vacuum contacts of high and medium voltage switches or circuit breakers
Electrodes for EDM
High temperature resistant materials
Radiator used in electronic equipment
Electrodes for resistance welding
Electronic packaging and heat sink materials
High-power devices such as microwave, laser, radio frequency, optical communication, etc.
High-performance lead frame
Thermal control boards and radiators for military and civilian thermal control devices, etc.
Tungsten Copper Alloy (Tungsten W=70 Copper Cu=30)
Conductivity%IACS≥42
Density=14g/cm3
Softening temperature℃≥700
Tensile strength≥66Mpa
Hardness ≥184HV
Tungsten-copper alloy can withstand high temperature and high stress of nearly 2000 degrees, has the characteristics of high melting point, high hardness, anti-burning and good anti-adhesion. The electro-erosion products have high surface finish, high precision and low loss.
The production process of tungsten copper alloy:
Tungsten copper is an alloy of tungsten and copper. The tungsten-copper alloy is made of fine tungsten and copper powders, through the first-class infiltration sintering process, and refined by the process of isostatic pressing-high temperature sintering tungsten skeleton-infiltration copper.
