Tungsten ore is a rock or mineral containing tungsten in its compound form. The ore minerals of tungsten include wolframite, scheelite, and ferberite. Tungsten is used for making many alloys. Tungsten ore deposits are predominantly magmatic or hydrothermal in origin and are associated with felsic igneous intrusions.
In nature, it primarily exists as a hexavalent cation with an ionic radius of approximately 0.68 10 m. Due to its small ion size, high electrostatic charge, strong polarization ability, and tendency to form complex anions, tungsten is commonly found in the form of [WO]. These anions interact with cations such as Fe, Mn, and Ca in solution, leading to the precipitation of minerals like wolframite and scheelite.

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.
