What Is An Alloy | Alloy Definition | Alloy Wiki

15/7/2021· Pure aluminum has a low density of 2.7 g/cm3, good thermal and electrical conductivity (second only to Au, Ag, Cu), good ductility and high plasticity, and can be processed by various machining. The chemical properties of aluminum are active, and it oxidizes rapidly in the air to form a dense and firm oxide film, which has good corrosion resistance.

Aluminum Sheets & Plate | The Aluminum Association

Aluminum from 0.008 inches to less than 0.25 inches thick is considered sheet. Thinner aluminum is foil and aluminum 0.250 inches and thicker is plate. The colder, the stronger. Aluminum plate is used for storage tanks in many industries in part because some aluminum alloys gain strength at supercold temperatures.
