provide ANSI Standard Copper Tungsten Bars W85 W75 Machined Tungsten Copper Alloy CuW Bars The feature of the tungsten copperb bars Tungsten copper (copper tungsten, CuW, or WCu) alloy is a pseudo-alloy of tungsten and copper. 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.Tungsten copper 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. The tungsten copper bars have the better heat resistant and great ablate resistant. At the meantime, the tungsten copper bars have the high intensity and high density. The tungsten copper alloy has the excellent thermal and eletrical conductivity. And the tungsten copper alloy is easy to be machined. The bars are made from the tungsten copper alloy by pressing the tungsten particles into a desired shape, sintering the compacted part, and then infiltrating with molten copper. Sheets, rods and bars of tungsten copper alloy are available as well. Applicatioins of tungsten copper sheets Tungsten copper alloy bars are used worldwide for EDM (Electrical Discharge Machining) and ECM (Electrochemical Machining) electrodes. All the tungsten copper alloy is manufactured by the press, sinter, and infiltrate process. Virgin tungsten powders are used, resulting in a consistent homogeneous material, which gives the high and even burning rates. Tungsten copper is used in plunger and sinker. Applications where intricate definition is required, especially in tungsten carbide. The advantages of the tungsten copper bars 1. The high heat resistant. 2. The better ablate-resistant. 3. The great electrical conductivity

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.
