1100 aluminum circles are circular aluminum products manufactured from 1100 aluminum sheet through processes such as stamping, spinning, and deep drawing. Belonging to the 1000 series of commercially pure aluminum alloys, they contain at least 99.0% aluminum. The addition of a small amount of copper to the pure aluminum gives the 1100 alloy higher strength than the 1050, 1060, and 1070 grades, while it retains excellent ductility, corrosion resistance, thermal conductivity, and weldability. 1100 aluminum circles are widely used in the manufacture of cookware, lighting fixtures, food packaging, chemical equipment, and electronic products, as well as in the production of various deep-drawn, spun, and stamped parts.
Description
Features
