Copper Tungsten has a wider range of uses

Copper Tungsten alloy composite material is a two-phase structure pseudo-alloy composed mainly of tungsten and copper, which is a metal-based composite material. Due to the large difference of the physical properties of copper and tungsten, it can not be produced by the casting method, Alloy technology for production.

Tungsten copper alloy has a wider range of uses, most of which are used in aerospace, aviation, electronics, power, metallurgy, machinery, sports equipment and other industries. Secondly, it should also be used to manufacture the contacts of the high-voltage electrical switches resistant to arc ablation and the rocket nozzle throat lining and tail rudder and other high-temperature components as well as the electrodes for electrical processing, high-temperature molds and other applications requiring electrical and thermal conductivity and high temperature occasion.

Tungsten comes from a kind of white sand type ore body. The ore line is particularly small. The tungsten ore powder with the grade above 95% is obtained through multi-channel processes such as digging, grinding, water re-election and refining etc., The finished product is tungsten. Tungsten gold melting point: 3500 ℃. Tungsten is currently mainly distributed in China and Russia, China is now the world’s largest tungsten exporter. Usually tungsten gold purity should be more than 99.95_, and must be issued by the authority of the test analysis and test reports.

Uses Unique tungsten has many unique uses, such as the high hardness of tungsten that can make tungsten steel. Made of tungsten steel tools, several times higher than the strength of ordinary steel tools and even dozens of times; with tungsten steel barrel, gun barrel, in a continuous shooting, even if the barrel is scalded by projectile hot, still maintain good flexibility And mechanical strength. In the metal cutting machine, with tungsten steel turning tool, the temperature can reach as high as 1000 ℃ still as before.

Spraying or surfacing stellite steels containing between 3% and 15% tungsten on common steel parts equals putting hard « armor » on the part, which is resistant to both temperature and pressure as well as to corrosion and corrosion resistance Wear and tear, the service life can be extended several times. Due to the superior properties and the wide range of uses of tungsten steel, 90% of tungsten produced annually in the world is used to make tungsten steel. Cobalt-Chromium Alloy plasticity.

Copper Tungsten alloy in the detection of tungsten-copper alloy hardness

Copper Tungsten alloy in the detection of tungsten-copper alloy hardness, its shape and size of the specimen adaptability is relatively strong, and the test efficiency is relatively high, the most important is the hardness and other physical properties of tungsten-copper alloy there is a correspondence relationship. When we carry out tungsten-copper alloy, but also to detect the ability of the metal to resist plastic deformation, this test from a certain point of view there are some commonalities, so the test results for the tungsten-copper alloy, we can compare with each other.

Copper tungsten alloy material is a kind of metal composite material, which is called tungsten-copper alloy because its name suggests is that it is made of two materials, tungsten and copper, and the composite material can also be widely used in many Industry, so today we take a look at what areas in our country can be frequently used tungsten-copper alloy it?

First of all, this composite material combines the advantages of two metal products, copper and tungsten. If one can first understand the advantages of tungsten and copper, one can still know a little about tungsten and copper alloys.

Copper tungsten alloy can be high temperature, density is also great, thermal conductivity and conductivity is moderate, the intensity is also high, so this performance is doomed tungsten-copper alloy can be used in many areas. For example, it can be used in aerospace as a missile air rudder, nozzle, gas rudder, which is the use of tungsten-copper alloy high temperature performance.

Copper tungsten alloy is widely used in high voltage switch 128kV SF6 circuit breaker WCu / CuCr, as well as high voltage vacuum load switch and arrester. The high voltage vacuum switch is small in size and easy to maintain. It is widely used in humid, flammable, explosive and corrosion Use of the environment.More Cobalt-Chromium Alloy Manufacturer in China.

Cobaltalloy Talk about Silver Tungsten

Preparation of Silver Tungsten alloy and tungsten copper alloy the same. Because of the high melting point of tungsten and silver can not be mutual melting, it can not be prepared by traditional methods, the preparation of tungsten silver alloy powder metallurgy method must be used. The application of tungsten silver alloy and tungsten copper alloy is also relatively similar, tungsten silver alloy used as a solid rocket nozzle throat lining. In the electrical switch, tungsten silver alloy more for lower voltage circuit breakers, automatic switches, contactors and other requirements of good oxidation resistance, conductive thermal conductivity, contact size smaller, frequent opening and closing of the occasion.

W-Ag alloy is widely used in high temperature materials, high voltage switchgear alloy, electric processing electrodes, microelectronic materials, as components and components widely used in aerospace, aviation, electronics, power, metallurgy, machinery, sports equipment and other industries .

High temperature oxidation resistance of silver-tungsten alloy, at room temperature does not react with the acid, but in a mixed acid nitric acid and hydrofluoric acid dissolved at 1000 ℃ in nitrogen atmosphere to form nitrides. Mechanical manufacturing according to advanced technology drawings after conversion in the production of lead bronze centrifugal casting technology, however, customs can not get foreign orders, due to the price is too high, and some use of alternative copper alloy production, resulting in life is too short, causing great Troubled.

In the actual production process, as long as the reasonable choice of surfacing process, surfacing layer weld metal to avoid chemical loss and impurities infiltration, dilution rate control under the premise of the quality and performance of the deposited can be guaranteed. In the course of this alloy carbide phase precipitation continued to become brittle.

Preparation of silver tungsten powder metallurgy, more than 60% of the tungsten alloy after immersion greater capacity. Mainly used for low voltage power switch, lifting switch, switch locomotive, high current switch contacts, heavy duty relays, air circuit breakers and other cobalt. These can improve wet silver tungsten, in order to reduce the ability to contact resistance. Cobalt-Chromium Alloy – »
