Iron is the most commonly used metal in the world. It is metallic-gray in color, ductile, ferromagnetic, and rusts easily when exposed to oxygen. It has a melting point of 1,535°C, a density of 7.86 g/cc, and a vapor pressure of 10-4 Torr at 1,180°C. Iron is found in a vast array of products including tools, automobiles, and machinery. When alloyed with carbon, steel is created which is an essential component for building construction and automobile manufacturing. Iron also has biological importance as it is responsible for carrying oxygen in blood. It is evaporated under vacuum to form layers in the production of semiconductors, magnetic storage media, and fuel cells, just to name a few.

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.
