Tungsten Carbide Copper Rod

Copper tungsten alloys are commonly used in EDM electrodes and other electrical and electrical/thermal applications. They are also used for facing and inserts for flash and butt welding dies, projection welding electrodes, seam welding bearing inserts and facing for electro-forming and electro-forging dies.
Although they are somewhat more difficult to machine, tungsten carbide copper materials provide high mechanical properties and excellent resistance to erosion. They are commonly used in oil devices to protect the contact from oxidation.

Copper Tungsten Electrode

Copper tungsten electrode's symbol is WCu. It has good physical and mechanical properties, such as high thermal and electrical conductivity. As to its supply state, copper tungsten electrode can be offered in sintering, tuming, grinding and finishing.
The technique of copper tungsten electrode is copper infiltered tungsten block in vacuum high temperature stove. During processing, proportion of copper and tungsten can be 60W/Cu, 70W/Cu, 75W/Cu, 80W/Cu, 85W/Cu, and 90W/Cu.
Copper tungsten electrode is widely used in sealed cap for transistors sealing welder, contactor materials for high-voltage switches, electrodes for spark processing, circuit breakers, and etc.

Tungsten Copper Sheet

Copper Tungsten sheet IntroduceTungsten Copper Alloy (Copper Tungsten, CuW, or WCu) is a pseudo-alloy of copper and tungsten. 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.
The 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. Parts are made from the WCu alloy by pressing the tungsten particles into a desired shape, sintering the compacted part, then infiltrating with molten copper. Sheets, rods and bars of the alloy are available as well.
Tungsten copper alloy sheet Advantages* High arc and temperature resistance
* Good electrical conductivity combined with high thermal conductivity
* Low thermal expansion

What is Tungsten Copper Alloy Bar

Tungsten copper alloy bar is integrates the advantages of tungsten and copper, within which tungsten’s melting point is higher( about 3410 ℃) and density is larger (about 19.34g/cm3). Tungsten copper alloy is easy to be machined, and is widely used in spaceflight, aviation, electron, electronic power, metallurgy, mechanism etc.

Tungsten copper alloy has different objects, such as rod, flat, bar, square, circle, ring, pipe, tube, bush and so on. And tungsten copper alloy bar is a kind of tungsten copper alloy, whose shape is bar, its transverse surface could be polygon, round or any other shape that you want. Chinatungsten supply tungsten copper alloy bar of high physical and mechanical properties, and we cut it to customers' desired lengths in diameters between 50.8mm to 19050mm. In addition, we set from Dia.1mm to Dia. 60mm, length 200mm tungsten copper alloy bar as standard. What’s more, Chinatungsten offer three different surface processes or finishes according to your demand: black, cleaned and ground.

Tungsten Copper Alloy Bar, the advantages of:
High conductivity, high temperature sintering, and melting refined copper are from the process of composite materials. In addition, there are arc off a good performance, good thermal conductivity, thermal expansion of small, high-temperature non-softening, high-intensity, high-density, high hardness and so on.

Copper Tungsten Bar Application

Copper tungsten bar is widely used to make Grid siderod, Lead, Support, and Electrode for the Gas discharge lamp, because of the high electrical conductivity and low consumption.
1. Resistance welding electrode
Copper tungsten bar integrates such features of tungsten and copper as high temperature resistance, electrical arc ablation resistance, high proportion, good electrical and heat conductivity, being easy to cut and transpiration cooling. It also owns such advantages of tungsten as high hardness, melting point and adherence resistance. It is often used for projection welding and butt-welding electrode with wear and high temperature resistance.
2. Electric spark electrode
Copper tungsten bar is used for the electrode of mould made from tungsten steel and high-temperature and ultra hard alloy. The common electrode has high consumption and low rate. The high electrical ablation rate, low consumption ratio, precise electrode size and quality processing performance of Copper tungsten can ensure that the precision of the work piece is greatly enhanced.
3. High-voltage discharge tube electrode
When the high-voltage vacuum discharge tube is working, the temperature of contact material will rise to thousands degree centigrade within several tenths seconds. High ablation resistance, high toughness, good electrical and heat conductivity of Copper tungsten provide necessary conditions to stable operation of the discharge tube.
4. Electrical seal material
Copper tungsten bar owns not only the low expansion of tungsten and high heat conductivity of copper. Its expansion index and heat conductivity can also be changed through changing the content of the materials, which provides convenience to the using of the material. We can supply various specifications and the Copper tungsten alloys with different tungsten proportions.

Copper Tungsten Bar Description

Copper tungsten bar is the composite of tungsten and copper, which own the excellent performances of tungsten and copper, such as heat-resistant, ablate-resistant, high-intensity, excellent thermal and electrical conductivity. It is easy to be machined. It is used widely in such industries as engine, electrical power, electron, metallurgy, spaceflight and aviation. Using CIP formation, sintered tungsten skeleton and infiltrating copper (silver) technology, large size and special shape products of tungsten-copper (silver) composites with 6-90 percent of copper are produced, such as electric contacts, electrode, refractory parts, heat sinks and parts of rocket, We can also produce sheet material, tubing, plate and other small products by mould pressing, extrusion pressing and MIM.
