Al(pellets & pieces)

Aluminum is one of the most common metals in the world. It can be found in kitchen utensils, cars, street lights, and the popular aluminum foil food packaging. Aluminum is a silvery-white, metallic material. It is light, malleable, ductile, and non-magnetic under normal conditions. It has a density of 2.7 g/cc, a melting point of 660°C, and a vapor pressure of 10-4 Torr at 1,010°C. Although it is not a strong material, it is a good conductor of heat and electricity and is able to form an oxide layer that is resistant to corrosion. Due to its high reactivity, it is rarely found in nature as a free element. When evaporated in a vacuum, aluminum layers form a reflective coating found on telescopes, automotive headlamps, mirrors, packages, and toys. It is widely used in the aerospace, automotive lighting, OLED, and optical industries.

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.
