Copper tungsten rod material is an alloy of tungsten and copper, which combines the advantages of tungsten and copper, high temperature resistance, arc ablation resistance, high strength, high specific gravity, electrical conductivity, thermal conductivity, easy cutting and processing, and sweating cooling characteristics. As vacuum contact materials, electrode materials, electronic packaging materials and rocket, missile special-purpose materials, etc. are widely used in machinery, power, electronics, metallurgy, aerospace and other industries.
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 bar grade: WD10070;
Model: 55W45Cu, 68W32Cu, 70W30Cu, 75W25Cu, 80W20Cu, 85W15Cu,
90W10Cu.
