Nov 30, 2009· Activation of tungsten (W) for non-cyanide Copper or Acid copper plating? November 30, 2009. Q. Greetings, My name is Rocco Basilica, process engineer for ODIS, Inc. I would like to plate approx. 1 micron copper onto some refractory metal (tungsten) features (smallest feature about 3 microns) for heat sinking purposes .
Tungsten-Copper for SF 6 circuit breakers.. Tungsten copper (WCu) materials are used for arcing contacts in SF 6 circuit breakers for high and medium voltage applications. At the heart of the switching chamber, WCu arcing contacts are exposed to extreme mechanical and thermal stresses.
Copper–tungsten (tungsten–copper, CuW, or WCu) is a mixture of copper and tungsten. 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 instead of a true alloy.
A method of separating tungsten from molybdenum wherein impure acid leached molybdenum trioxide containing tungsten is combined with ammonium hydroxide to form an ammonium molybdate solution, the solution is contacted with tin (IV) oxide hydrate to cause sorption of essentially all of the tungsten contained therein without causing sorption of molybdenum, the tin (IV) oxide hydrate with the ...
Tungsten copper heat sink is a composite of tungsten and copper. The coefficient of thermal expansion (CTE) of the composite can be designed by controlling the content of tungsten, matching that of the materials, such as Ceramics (Al2O3, …
contents of Tungsten respectively Copper can be selected. Tungsten-Copper combines many typical characteristics of the single elements Tungsten and Copper as for example the hardness, wear and burn-off resistance of Tungs-ten together with the good electrical and thermal conductivity of Copper.

Tungsten hexachloride is separated from a mixture of metal chlorides comprising tungsten pentachloride and other metal chlorides by first distilling the mixture so as to remove lower boiling chlorides than tungsten pentachloride. The mixture is then chlorinated, preferably at a temperature around that of the boiling point of the tungsten pentachloride.
