Ultra high purity tungsten (5N or 6N) is often used as a gate, link and barrier metal in the electronic industry due to its high resistance to electron migration, high temperature stability and the formation of stable silicides. The ultra-high pure tungsten and tungsten or tungsten titanium silicon composite material is often made of sputtering target materials with high purity, in the form of the film covered on the substrate or other thin film layer, for very large-scale integrated circuit as a resistance layer, a diffusion barrier layer and the metal oxide semiconductor transistor as the gate material and link materials.

Tungsten heavy alloys is a kind of alloy made by liquid-phase sintering process with Tungsten as the basic element and Ni, Cu, Fe and other elements added at the same time. Its density is up to 16.6 ~ 19.0g/cm3. It has outstanding physical and mechanical properties such as high density, good strength, low thermal expansion coefficient and good machining performance. Tungsten heavy alloys can be divided into large series: W-Ni-Cu series and W-Ni-Fe series, the former is non-magnetic alloy, the latter is magnetic alloy. W-Ni-Fe series alloys are widely used because of their better mechanical properties than W-Ni-Cu series alloys.

Tungsten carbide is widely used in industry because of its extraordinary properties. Because of its wear resistance and hardness (9.8 Moe's scale), tungsten carbide is ideally suited for wear parts, other machine parts and dies which are subject to severe service conditions, such as high temperatures, corrosion and abrasion.. In recent years, tungsten carbide has emerged as a superior alternative to steel in many industrial applications.
99.95% Pure Tungsten Products Tungsten Crucibles W Crucible for Sapphire Growing Because of the high melting point(3410) of tungsten, tungsten crucible is widely used in the industrial furnaces such as sapphire single crystal growth furnace, quartz glass melting furnace, rare earth smelting furnace and other industrial furnaces of which the working temperature is over 2000â??. Especially for sapphire single crystal growth furnace, tungsten crucible with features of high purity, high density, no crack, precise size, smoothy internal and external wall is the key note to seed success rate, crystal quality control, off crystal stick pan and service life in sapphire crystal growth process. During sapphire production, Al2O3 - the compound that is to become the future single crystal - is melted in tungsten crucibles. It is in the Kyropoulos process that our crucibles show their strengths to best effect. They arerepeatedly heated to more than 2 000 �°C (3632 �°F) and then cooled down again. This process, which would cause fissures and distortions in other materials, is not a problem for our products.
www.fotmacarbide.com provide Tungsten Copper Alloy Electrical Contacts Customized Arcing Contacts / Arc Runner Tungsten copper alloy can be used in oil-filled devices, air and gas circuit breakers, contactors, and high voltage switch gear. Some common applications are: arcing contacts and plates, arc runners , current carrying members, blade facings etc. The CuW75 tungsten copper alloy, with 75% of tungsten, is widely used in chip carriers, substrates, flanges and frames for power semiconductor devices. The high thermal conductivity of copper together with the low thermal expansion of tungsten allows thermal expansion matching to silicon, gallium arsenide, and some ceramics. Applicatioins of WCu Alloy HV Contacts: The high Electrical & thermal conductivity of copper are combined with the arc-resistant & non-welding properties of tungsten or their carbides to form an extensive series of compositions each designed to give the best performance for your particular application. These materials are used for such heavy duty contact applications as: Circuit breakers, air & oil immersed Arcing tips or arc runners Make & break contacts Heavy duty conductors, relays & switches. Advantages of Copper Tungsten Contacts: The high electrical and thermal conductivity of tungsten copper alloy allows a cool, effective transfer of power, while the excellent arc-resistance properties of tungsten copper minimize arc erosion and transfer problems. These characteristics can be varied by composition more silver or copper yields higher electrical and thermal conductivity, while a higher refractory metal content results in superior arc erosion properties. We offer a variety of composites to meet your demands. Regardless of the environment (oil-filled devices, air and gas circuit breakers, contactors, high voltage switch gear) or the application (arcing contacts and plates, arc runners, current carrying members and blade facings), you won't be disappointed in electrical contacts made from our copper tungsten composites.

Tungsten Heavy Alloys (WHAs) are tungsten alloys that typically contain 90 to 98 wt% W. Most commercial tungsten alloys are two-phase structures, the principal phase being nearly pure tungsten in association with a binder phase containing the transition metals plus dissolved tungsten. As a consequence, WHAs derives their fundamental properties from those of the principal tungsten phase, which provides for both high density and high elastic stiffness. It is these two properties that give rise to must applications for this family of materials.
