JINXING MATECH adopts isostatic pressing-high temperature sintering tungsten skeleton-copper infiltration process to produce various large and special-shaped parts with a copper content of 6-90%. The product has high purity, uniform structure and excellent performance. It can produce various sheets, rods, pipes, plates and small-sized products with complex shapes by compression molding, extrusion molding, and injection molding.
Tungsten Copper Rod, ASTM B702 RWMA Class 10,Class 11, Class 12
The tungsten copper bar is an alloy composed of tungsten and copper, and the copper content of the commonly used alloy is 10% to 50%. The alloy is prepared by powder metallurgy method and has good electrical and thermal conductivity, good high temperature strength and certain plasticity. At very high temperatures, such as above 3000C, the copper in the alloy is liquefied and evaporated.
- Description
The tungsten copper rod is an alloy composed of tungsten and copper, and the copper content of the commonly used alloy is 10% to 50%. The alloy is prepared by powder metallurgy method and has good electrical and thermal conductivity, good high temperature strength and certain plasticity. At very high temperatures, such as above 3000C, the copper in the alloy is liquefied and evaporated, which absorbs a large amount of heat and lowers the surface temperature of the material. So this type of material is also known as metal sweating material.
