Production process of Copper Tungsten Rods
tungsten copper used when a product or part needs to have a high
heat resistance, low thermal expansion and high electrical or
thermal conductivity. Copper Tungsten Rods 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.
The main use of Copper Tungsten Rods:
Tungsten copper alloy is widely used as the contact and protection
ring of high-voltage and ultra-hydraulic switches and circuit
breakers, thick anvil material of electric heating pier, automatic
submerged arc welding contact tip, plasma cutting machine nozzle,
and also used in electric welding machine and butt welding machine.
Welding heads and seam welding wheels are also used to make
gas-sealing electrodes and electric spark electrodes, spot welding,
butt welding materials, etc.
EDM electrode: When the mold made of tungsten steel and high
temperature resistant super hard alloy needs electric corrosion,
the ordinary electrode wears large and the speed is slow. The
characteristics of high electrical corrosion rate, low loss rate,
precise electrode shape, and excellent processing performance of
tungsten copper alloy greatly improve the accuracy of the
workpiece.
