Production process of Tungsten Copper Alloy Rod With Cu25W75 :
Tungsten copper is an alloy of tungsten and copper. The tungsten copper alloy is made of fine tungsten and copper powder through first-class infiltration sintering process and the process of isostatic pressing forming high-temperature sintering tungsten skeleton dissolving copper.
Main uses of tungsten copper alloy:
Tungsten Copper Alloy Rod With Cu25W75 is widely used as contact and protective ring of high-voltage and ultra-hydraulic switch and circuit breaker, thick anvil material of electric heating pier, conductive nozzle of automatic submerged arc welding, nozzle of plasma cutting machine, welding head and roll welding wheel of electric welding machine and butt welding machine, as well as gas sealing electrode and electric spark electrode, spot welding and bump welding materials
Tungsten Copper Alloy Rod With Cu25W75 Picture:
1. Resistance welding electrode: tungsten copper alloy combines the advantages of tungsten and copper. It has the characteristics of high temperature resistance, arc ablation resistance, high strength, large ratio, good conductivity, good thermal conductivity, easy cutting and cooling, etc. Because tungsten copper alloy has the characteristics of high hardness, high melting point and anti adhesion of tungsten, it is often used as projection welding and butt welding electrode with certain wear resistance and high temperature resistance.
2. Electric spark electrode: when the mold made of tungsten steel and high temperature resistant superhard alloy needs electric corrosion, the loss of ordinary electrode is large and the speed is slow. The characteristics of tungsten copper alloy such as high electric corrosion rate, low loss rate, accurate electrode shape and excellent machining performance can greatly improve the accuracy of machined parts.
3. Electrode of high-voltage discharge tube: when the high-voltage vacuum discharge tube is working, the temperature of contact material will rise by thousands of degrees Celsius in a few tenths of a second. The high ablation resistance, high toughness, good conductivity and thermal conductivity of tungsten copper alloy provide necessary conditions for the stable operation of discharge tube.
4. Electronic packaging materials: tungsten copper alloy not only has the low expansion characteristics of tungsten, but also has the high thermal conductivity of copper.
The thermal expansion coefficient and conductivity of tungsten copper alloy can be changed by adjusting the composition of the material, which provides convenience for the use of the material.
