Copper tungsten composite material

Copper Tungsten alloy composite material is made of tungsten and copper are two mutually false solution alloy metal, which combines the high electrical conductivity of tungsten melting point, high hardness, low coefficient of expansion and copper. Is a very good performance composites. Copper Tungsten alloy Material not only has good thermal conductivity and low coefficient of thermal expansion, but also by changing the content of tungsten to the design of its thermal conductivity and expansion coefficient, these features make the tungsten-copper composite material in high temperature, high pressure switch with electrical alloy , EDM electrode, microelectronic materials, as parts and components.

The main purpose of copper-tungsten alloy

Copper Tungsten alloy is mainly used in:

2. Contact Material: High pressure switch or circuit breaker arcing contacts and vacuum contacts, circuit board welding and electrical contact points.
3. Welding Material: submerged arc welding machine, gas shielded welding tip, radio resistor factory (production of carbon film resistors, metal coating resistance) Resistance Welder Welding materials (Copper Tungsten alloy

welding disc).

4. guides materials: wire rod mill, for guiding the protective effect of the material.

Copper tungsten electrode material

Our company have high-quality domestic Copper Tungsten alloy material, very suitable for high hardness materials and thin electrical discharge machining, EDM product surface finish, high precision, low loss, effective conservation of the electrode material to increase the discharge machining speed and improved precision molds . Another useful as spot welding / Welding electrodes. copper tungsten and tool steel welded into one, in a very easy to use electrodes.

The application of Use copper tungsten alloy

Copper Tungsten alloy is combines the advantages of copper and tungsten, high strength / high specific gravity / high-temperature / low arc ablation / thermal conductivity properties / Good processing performance, ANK copper alloy of Tungsten powder and tungsten high-quality oxygen-free copper powder, and applications isostatic pressing - (high temperature sintering) - copper infiltration, to ensure product purity and accuracy ratio, fine organization and excellent performance.

Copper tungsten can be used as armor materials

Sunder material is a so-called "Liner" materials. Cover made of Copper Tungsten alloy (material commonly used W-30Cu) cup-shaped or funnel-shaped, flip to the front end of Jane's ammunition, gunpowder temperature and pressure by the cover is deformed into a jet and piercing. This Liner first used copper manufacturing, and a large number of applications. In order to increase the quality of the cover unit to improve armor capability, and later research unit mass is larger than the guillotine Copper Tungsten alloy liner, in the ideal case, it is higher than the capacity of copper armor cover about 30%.

Military high temperature materials

Copper Tungsten alloy Parts is used as missiles in aerospace, the rocket engine nozzle, gas rudder, air rudder, the nose, the main requirement is to require high temperature (3000K ~ 5000K), high temperature air erosion capacity, the main use of copper at high temperatures sweating refrigeration volatile form of (copper melting point of 1083 ℃), reducing the surface temperature of Copper Tungsten alloy, ensure that the use in extreme conditions at high temperatures.

The physical properties of copper-tungsten alloy

Copper Tungsten alloy combines the advantages of tungsten and copper, in which a high melting point of tungsten (tungsten metals melting point of 3410 ℃, copper melting point 1080 ℃), high density (tungsten density of 19.25g / cm, copper density of 8.92 / cm3); excellent thermal conductivity properties of copper, tungsten copper alloy (composition generally ranges WCu7 ~ WCu50) uniform microstructure, high temperature, high strength, resistance to arc erosion, high density; moderate conductivity, thermal conductivity, high temperature materials are widely used in military, high-voltage switch with electrical alloy, EDM electrode, microelectronic materials, parts and components as widely used in aerospace, aviation, electronics, electricity, metallurgy, machinery, sports equipment and other industries.

The use of tungsten copper

Selection of fine Copper Tungsten alloy, tungsten copper powder, soaked by class sintering process is refined, can withstand nearly 2,000 high temperature and high stress, high melting point, high hardness, resistance to burning and good adhesion resistance, electrolytic corrosion product surface finish high, high precision, low loss. Copper tungsten is widely used as a high-voltage, ultra-hydraulic switch contacts and circuit breakers, protection ring, electric upsetting anvil block material for conductive Tsui automatic submerged arc welding, plasma cutting machine nozzles, welding, welding welding head , seam welding wheel, sealed gas Mao electrode and spark electrode point, spot welding, butt welding materials.

Performance of copper tungsten alloy

Since Copper Tungsten alloy has good electrical and thermal conductivity, good high temperature strength and a certain plasticity. Copper Tungsten alloy has a broader purpose, mainly used to make contacts and rocket nozzle throat insert, rudder and other high-temperature components of the anti-high-voltage electrical arc ablation switch is also used as EDM electrodes, high temperature molds and other requirements thermal conductivity properties of high temperature and occasions.

What is tungsten copper alloy

Tungsten and tungsten alloy composed of copper is called Copper Tungsten alloy, it is used the amount of 10% to 50%. Preparation Copper Tungsten alloy powder metallurgy method has good electrical and thermal conductivity, good high temperature strength and a certain plasticity. At very high temperatures, such as above 3000 ℃, the alloy of copper is liquefied and evaporated to absorb a lot of heat, reducing the surface temperature. So this kind of material is also referred to as metal sweat material.
