Copper tungsten rod welding electrode RWMA Class 10,Class 11, Class
12 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.

Copper tungsten rod are widely used where the combination of
good electrical and/or thermal conductivity and low thermal
deformation is necessary, for example:· In electric resistance
welding as electrical contacts or heat sinks.· In electrodes for
electrical discharge machining (EDM) and electrochemical machining
(ECM). |
