Tungsten (W) Pellets Evaporation Materials
Tungsten, also known as Wolfram, is one of the densest elements in the world. It has a density of 19.25 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.

Titanium is a common material found in a myriad of products including watches, drill bits, laptops, and bicycles, just to name a few. In pure form, it is lustrous and silvery-white in appearance. It has a melting point of 1,660°C, a density of 4.5 g/cc, and a vapor pressure of 10-4Torr at 1,453°C. It is a sturdy material which is easily fabricated when heat is applied. Its strong, lightweight characteristics and excellent corrosion resistance make it ideal for ocean liner hulls, aircraft engines, and designer jewelry. Titanium is biocompatible so it can be found in surgical tools and implants. Titanium is generally evaporated in vacuum for the purposes of wear and decorative, semiconductor, and optical coatings.
