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.

High quality products have been made after decades of procedures such as pressing, sintering, rolling, cutting and surface grinding. Super sputtering target (single heavy reach to 120kg) is available at present. Tungsten Hollow Rods Description: Purity: Wâ?¥99.95% Density: more than 19.1g/cm3 Tolerance: +/-0.05mm Supply state: Surface polishing, CNC machine processing Quality standard: ASTM B760-86, GB 3875-83
www.fotamcarbide.com provide 99.95% Pure Tungsten Products Tungsten Crucibles W Crucible for Sapphire Growing Because of the high melting point(3410â??) 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.
Cobalt-chromium-molybdenum alloy (CoCrMo) is a kind of cobalt-based alloy, and is also a kind of Stellite alloy. It is a cobalt-based alloy that is resistant to wear and corrosion. The first cobalt-based alloy was a cobalt-chromium binary alloy, which was later developed into a cobalt-chromium-tungsten ternary composition, and then later did the cobalt-chromium-molybdenum alloy develop. Cobalt-chromium-molybdenum alloy is a kind of alloy with cobalt as the main component, containing a considerable amount of chromium, molybdenum and a small amount of nickel, carbon and other alloying elements, and occasionally also containing iron.

www.fotmacarbide.com provide CuW75 Customized Tungsten Copper Alloy Heat Sinks WCu Spreader For LED Industry The CuW75 tungsten copper alloy is used extensively in thermal mounting plates, heat sinks, chip carriers, flanges, and frames for high-power electronic devices. As a tungsten copper material, it's a composite, so both the thermal advantages of copper and the very low expansion characteristics of tungsten can be utilized. The combination of tungsten & copper materials results in thermal expansion characteristics similar to those of silicone carbide, aluminum oxide, and beryllium oxide, used as chips and substrates. Because of tungsten copperâ??s thermal conductivity and expansion characteristics, Tungsten copper alloy works well in densely packed circuits. The thermal conductivity and thermal expansion characteristics of the semiconductor and the base plate must be optimally harmonized to avoid undesired distortions to the semiconductor. The better harmonized the properties are, the better the semiconductor module is to withstand soldering processes involved during manufacture and the temperature cycles that occur during operation. The sketch shows the principle structure of a hermetically sealed electronic package. Advantages of Copper Tungsten Heat Sinks / Spreaders: Strong hardness(86~93.5HRA) High arc resistance combined with good electrical conductivity High thermal conductivity Low thermal expansion. Applicatioins of Tungsten Copper Alloy: Our tungsten copper composites to be used extensively in thermal mounting plates, chip carriers, flanges, and frames for high-powered electronic devices. With the thermal advantages of copper with the very low expansion characteristics of tungsten, tungsten copper has properties similar to those of silicone carbide, aluminum oxide, and beryllium oxide. The thermal conductivity and low expansion also make tungsten copper alloy an excellent choice even for extremely dense circuits.
