Cobalt is one of the most widely recognized metals in the world. It has a density of 8.9 g/cc, a melting point of 1,495°C, and a vapor pressure of 10-4 Torr at 1,200°C. It is a lustrous, hard metal that is gray in appearance and characteristically ferromagnetic. One of its most popular uses is as a blue pigment found in paint, jewelry, and glass. It is often alloyed with other metals to make engine parts and cutting tools. Its two main vacuum applications are as a ferromagnetic layer in the production of magnetic storage media and as a transitional layer in battery fabrication.

Vacuum evaporation means the evaporation materials are evaporated to atoms or molecules in vacuum by current heating, electron beam heating and laser heating. Atoms or molecules make rectilinear motion to impact substrate surface and condense to form films.
