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.

WebMar 1, 2015 · Theoretically, as the MS increases, the tungsten level in the cobalt binder phase would decrease. Based on the effects of alloying elements on the thermal expansion of materials, tungsten should decrease the thermal expansion of cobalt alloy phase, since the CTE of tungsten is less than the CTE of cobalt [27]. Therefore, overall CTE would ...
