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 contacts spares has 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.

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.

Tungsten Copper Melting Point

Tungsten Copper Alloy

The alloy which is used by taking copper and tungsten is known as copper tungsten alloy. Such alloys are pseudo alloys of tungsten and copper which means that their microstructure is a metal matrix composite and not really a true alloy. This happens because copper and tungsten are not mutually soluble when mixed together. When copper and tungsten are combined, the material which is obtained has properties of both copper and tungsten. The material which is obtained is heat-resistant, thermally conductive and has high electrical conductivity as well. These materials are also ablation resistant. This is the reason why this material is used for making copper tungsten electrodes.

Tungsten Copper Alloy Features

Tungsten copper is composite materials using excellent metal characteristic of high-purity tungsten powder, and good plasticity, high conductivity of high purity copper powder, by refining process of isocratic pressing, high temperature sintering, and dissolved copper infiltration. Good broken arc performance, good thermal conductivity, little thermal expansion, does not soften at high temperature, high strength, high density, and high hardness.

Tungsten copper has good electrical and thermal conductivity, good high temperature strength and certain plasticity. At very high temperatures, such as above 3000 ℃, the copper in alloy is liquefied and evaporated, absorbs heat, reduces the surface temperature. So this kind of material is also called metal sweating materials.

Tungsten Copper Thermal Conductivity

As the speed and degree of integration of semiconductor devices increases, more heat is generated, and the performance and lifetime of semiconductor devices depend on the dissipation of the generated heat. Tungsten copper alloys have high electrical and thermal conductivity, low contact resistances, and low coefficients of thermal expansion, thus allowing them to be used as a shielding material for microwave packages, and heat sinks for high power integrated circuits (ICs). In this study, the thermal conductivity and thermal expansion of several types of tungsten–copper (W–Cu) composites are investigated, using compositions of 5–30 wt.% copper balanced with tungsten. The tungsten–copper powders were produced using the spray conversion method, and the W–Cu alloys were fabricated via the metal injection molding. The tungsten–copper composite particles were nanosized, and the thermal conductivity of the W–Cu alloys gradually decreases with temperature increases. The thermal conductivity of the W–30 wt. % Cu composite was 238 W/(m K) at room temperature.

We present the temperature dependence of the thermophysical properties for tungsten–copper composite from room temperature to 400 °C. The powders of tungsten–copper were produced by the spray conversion method and the W–Cu alloys were fabricated by the metal injection molding. Thermal conductivity and thermal expansion of tungsten–copper composite was controllable by volume fraction copper.
