Tungsten Copper
OMT provides Tungsten copper rod, Tungsten copper plate, Tungsten copper cube, Tungsten copper ring, Tungsten copper block, Tungsten Copper electrode and other customized tungsten copper parts.
Tungsten based composites (tungsten copper & tungsten silver) are strong refractory metal materials manufactured by a strictly controlled process involving pressing, sintering and infiltrating with copper or silver (tungsten copper & tungsten silver) . Tungsten copper & tungsten silver materials are highly resistant to heat, electric arc, wear and deformation at high temperature welding, flash butt and spot welding. Tungsten copper & tungsten silver materials also have excellent electrical and thermal conductivity. The properties of Tungsten composites (tungsten copper & tungsten silver) are related to the copper/silver-to-Tungsten ratio. If the Tungsten content improves, the electric arc and wear resistance will increase while the thermal and electrical conductivity, on the contrary, reduce. Due to their unique properties, Tungsten copper & tungsten silver materials are widely used where the combination of good electrical and/or thermal conductivity and low thermal deformation is necessary
