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.

Copper infiltrated temperature is too high or too low affects the penetration effect.
Copper- infiltration on the quality of the copper layer has a great influence, the cooling rate is too fast to produce pores and cracks easily; the same time, due to the heterogeneity of the furnace temperature, the product copper layer thickness is not uniform, so after copper infiltrated using a special cooling process. In order to simplify the process, you can in a hot cycle to complete copper infiltrated and copper processes.

Tungsten Copper Alloy

Tungsten copper (copper tungsten, CuW, or WCu) alloy is a pseudo-alloyof tungsten and copper. As copper and tungsten are not mutually soluble, the material is composed of distinct particles of one metal dispersed in a matrix of the other one. The microstructure is therefore rather a metal matrix composite than a true alloy.Copper Tungsten alloy combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, highly thermally and electrically conductive, and easy to machine.

Tungsten Copper Alloy Main applications: For the spark erosion of dies of cemented carbide and for making high speed steel and switches and contacts in high and low voltage electrical devices.

Tungsten Copper materials

Electrical contacts are subjected to extreme mechanical and thermal stresses during operation. For fractions of a second, temperatures rise to several thousand degrees as a result of the arcing. Only Tungsten Copper materials will stand these high temperature & aberration.

Tungsten Copper material 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 Coppers are also used as arcing edges of selector switchblades in transformer tap changers.

Fine selection of tungsten copper tungsten, copper powder, soaked by the first-class sintering process is refined, and can withstand high temperature and high stress nearly 2,000, with a high melting point, high hardness, resistance to burning and good anti-adhesion, electrical erosion surface finish high, high precision, low loss. 

Tungsten Copper is widely used as high-voltage, ultra-contact switches and hydraulic breakers, protection ring, electric upsetting anvil material for conductive Tsui automatic submerged arc welding, plasma cutting machine nozzle, welding machine, welding machine welding head , seam welding wheels, air sealing point sockets spark electrode and the electrode, spot welding, butt welding materials.

Tungsten copper electronics package and the heat sink material

Tungsten copper electronics package and the heat sink material, both having low expansion characteristics of tungsten, and high thermal conductivity characteristics with copper, the thermal expansion coefficient and thermal conductivity can be varied by adjusting the tungsten and copper components, thus giving tungsten-copper provides a more a wide range of applications.

Since tungsten copper material having high heat resistance and good thermal conductivity, while the wafer, and the thermal expansion coefficient of the ceramic material GaAs match, it is widely used in the semiconductor material. Suitable for high-power devices and packaging materials, heat sink materials, cooling components, such as ceramics and gallium arsenide base.

Tungsten Copper Alloy

Tungsten Copper Alloy is a metal electrode material is theoretically the best, its strength, density, hardness is high, the melting point close to C3400 ℃, so the electric discharge machining and welding process,

the actual loss of the tungsten electrode is small, but for pure tungsten electrodes two problems: a difficult process, two expensive, so the use of the plasticity of copper, high conductivity, etc., made ​​of composite material, the electrodes become treasures - copper tungsten electrode.

Tungsten Copper Heat Sink Material

Tungsten copper heat sink material, both with low expansion characteristics of tungsten, but also has high thermal conductivity properties of copper, its thermal expansion coefficient and thermal conductivity can be varied by adjusting the composition of tungsten copper, tungsten, copper and thus to provide a wider application range.

Since tungsten copper material having high heat resistance and good thermal conductivity, while the wafer, and the thermal expansion coefficient of the ceramic material GaAs match, it is widely used in the semiconductor material. Suitable for high-power devices and packaging materials, heat sink materials, cooling components, such as ceramics and gallium arsenide base.
