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.

Raw melting material - aluminum scraps, cans, engine waste etc. Output capacity - 5-30 tons/h, customized Automation - Full automatic/ half automatic (based on output requirement and investment budget Ingot type - ADC12 (7.5kg/ 10kg / customized) 1. After cleaning the oil and grease of waste aluminum, manually put it into the furnace with a forklift; 2. Ignition for melting furnace .Heat up to 680C, and input appropriate proportion of alloy elements. Heat up to 800C, melt and stir evenly, then fetch samples to the spectrometer for testing. Every lot of production need to do testing . 3. Put A tool that attracts iron into the furnace by forklift, to suck away the iron in the aluminum water. 4. Put the slag agent into Alu liquid to remove the slag. After slag removed , put the slags into Aluminum ash separation machine , and let the aluminum water and ash separate. The proportion of slag agent and aluminum liquid is 1:500 5.Open the drain valve and the aluminum water flows automatically to the ingot production line After the ingot casting is completed, the ingot stacking robot will stack the ingots, which means the production is completed.
Key Properties of Copper Alloys Excellent heat conductivity. Excellent electrical conductivity. Good corrosion resistance. Good biofouling resistance. Good machinability. Retention of mechanical and electrical properties at cryogenic temperatures. Non-magnetic.
We hold immense expertise in making available Copper in many forms including LME registered and non registered cathodes, billets, rods, cakes, bars, foil, sheet, granules, plates, powder, shot, turnings, wire, insulated wire, mesh and “evaporation slugs”. Copper is one of the most important metals. Copper is reddish with a bright metallic lustre. It is malleable, ductile, and a good conductor of heat and electricity (second only to silver in electrical conductivity). Its alloys, brass and bronze, are very important. Monel and gun metals also contain copper. The most important compounds are the oxide and the sulphate, (blue vitriol
