Tungsten Copper Electrode Application

Tungsten copper electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit. And the composition of tungsten copper electrode is tungsten and copper.

Tungsten copper electrode owns the sprier properties of tungsten and copper, with which of high conductivity, good  thermal conductivity, thermal expansion of small, high-temperature non-softening, high-intensity, high-density and high hardness.
With these sprier properties, tungsten copper electrode are usual used in the following area:
1.Resistance welding
2.EDM field
3.High-voltage vacuum discharge tube
4.Electronic Packaging Materials

Tungsten Copper Contacts Spares

Chinatungsten are able to provide kinds of tungsten copper contacts, and the tungsten copper contacts spares is a kind of tungsten copper contacts. It is used as electrode.

Tungsten Copper Contact Spares Picture

Tungsten copper contacts spares have good resistance to arc erosion, mechanical wear, contact welding and good conductivity. They are usually selected for oil, gas, air or vacuum, devices. The contact surfaces will oxidize when switched in air. These press-sinter-infiltrate materials should only be considered for arcing surfaces in air when used as arcing tips, arc plates and arc runners. When switching with moderate contact arcing, the tungsten copper with a high copper content may give the lowest erosion. As arcing severity increases, the tungsten copper with the higher refractory content withstand arc erosion better. Tungsten copper contacts spares are also used as arcing edges of selector switchblades in transformer tap changers.

Tungsten copper contacts spares materials made of WCu are also characterized by the properties of high arc erosion resistance, good electrical conductivity, excellent strength, very good machinability, good thermal conductivity and low thermal expansion.

Tungsten Copper Wear Resistance

Tungsten copper wear resistance material for a lining of a blast-furnace tuyere sleeve, which is prepared by the following raw materials in percentage by weight: 40-60% of nano copper powder, 36-56% of nano tungsten powder, 0.2-0.65% of iron powder and 4-6% of chromium powder. Metal conducts plastic deformation and is molten and diffused at high temperature and high pressure and by the aging effect at the high temperature and the high pressure, so that the high-temperature wear-resistant tungsten copper material is obtained. The high temperature wear resistance  material of tungsten copper is good in heat-conducting property, high-temperature strength and high-temperature wear-resistant property, can realize metallurgical bonding with a fine copper substrate, and can be used for manufacturing the lining of the blast-furnace tuyere sleeve, which is good in wear-resistant property and long in service life; the wear-resistant property of the blast-furnace tuyere sleeve can be improved greatly; and the service life of the blast-furnace tuyere sleeve can be prolonged greatly.

Tungsten Copper Parts Picture

The tungsten copper wear resistance nano-powder materials were milled, depending on the ratio of copper powder mixed 2_4h, first at the bottom of the prepared graphite mold Xianpu about O. 5_ thick layer of pure nano-tungsten-copper resistant materials and then mixed in different proportions holes and pure copper powder powder, copper content increased, the thickness of about I. 5mm, the surface layer of about O. 5mm holes and ー thick pure copper powder.
