Description
Aluminium is one of the most widely used metals in the world. It can be found in kitchen utensils, cars, street lamps and the popular aluminium foil used for food packaging. Aluminium 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/cm³, a melting point of 660°C and a vapour pressure of 10-4 Torr at 1,010°C. Although not a strong material, it is a good conductor of heat and electricity and can form a corrosion resistant oxide film. Due to its high reactivity, it is rarely found as a free element in nature. When evaporated in a vacuum, layers of aluminium form a reflective coating that can be found on telescopes, car headlights, mirrors, packaging and toys. It is widely used in aerospace, automotive lighting, OLEDs and the optical industry.

* This is a recommendation based on our experience with these materials in our sputter guns. The rates are based on non-bonded targets and are material specific. Bonded targets should be operated at lower power to avoid bonding failure. Bonded targets should be operated at 20 watts/square inch or less depending on the material.
