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.

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 Alloy metals are mainly including W-Ni-Fe and W-Ni-Cu, are extensively used in military equipment, mechanical manufacturing, aircraft components, medical shields and sports equipment. WNiFe/WNiCu tungsten heavy tungsten heavy alloy WNiFe tungsten nickel ferro/iron alloy.
W-Ni-Fe alloy is used in collimator and shielding components to provide protection against X-ray and �³-ray radiation. A product manufactured from tungsten, nickel and copper, is distinctive due to its non-magnetic behavior. This material is used in the places to avoid magnetic interference.
