Tungsten (W) General Information

Tungsten, also known as Wolfram, is one of the densest elements in the world. It has a density of 19.3 g/cc, a melting point of 3,410°C, and a vapor pressure of 10-4 Torr at 2,757°C. It is lustrous and grayish-white in appearance. It is known to have the highest melting point of all metals and its characteristic hardness can make it very difficult to machine and forge in pure form. Tungsten is commonly used to make electric filaments. Tungsten carbide is found in drills, saws, and jewelry. Tungsten is evaporated under vacuum for the production of semiconductors, fuel cells, and sensors.

* This is a recommendation based on our experience running these materials in KJLC guns. The ratings are based on unbonded targets and are material specific. Bonded targets should be run at lower powers to prevent bonding failures. Bonded targets should be run at 20 Watts/Square Inch or lower, depending on the material.

* Suggested maximum power densities are based on using a sputter up orientation with optimal thermal transfer from target to the sputter cathode cooling well. Using other sputtering orientations or if there is a poor thermal interface between target to sputter cathode cooling well may require a reduction in suggested maximum power density and/or application of a thermal transfer paste. Please contact techinfo@lesker.com for specific power recommendations.
