WebLow CTE Copper Tungsten Electronic Packaging Materials WCu Heat Sink Description: CuW, also called copper tungsten, tungsten copper and W-Cu, is a powdered metal product consisting of a mixture of copper and tungsten (a.k.a. wolfram). ... By adjusting the content of tungsten, we can have its coefficient of thermal expansion (CTE) designed … Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements. It was identified as a new element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternate name.
