Aluminum Sputtering Target Description
The aluminum sputtering target has the same properties as metal aluminum. Aluminum is a silvery-white, soft, non-magnetic, and ductile metal in the boron group. By mass, aluminum makes up about 8% of the Earth’s crust; it is the third most abundant element after oxygen and silicon and the most abundant metal in the crust, though it is less common in the mantle below. The chief ore of aluminum is bauxite. Aluminum metal is highly reactive, such that native specimens are rare and limited to extreme reducing environments. Instead, it is found combined in over 270 different minerals. When evaporated in a vacuum, aluminum layers form a reflective coating found on telescopes, automotive headlamps, mirrors, packages, and toys. The aluminum sputter target is widely used in the aerospace, automotive lighting, OLED, and optical industries.
