The aluminum circle refers to round flat aluminum pieces used for production of cookware, lighting reflector and decorative parts. Also known as aluminum circle discs, it boasts good corrosion resistance, excellent deep drawing property and long service life. There are mainly 1xxx aluminum circles and 3000 series aluminium circle discs, including 1050, 1060, 1070, 1100 and 3003 etc. 1000 differs from 3000 in that it has weaker strength and anti-rust ability. Even stronger alloys, such as 5xxx and above, are not suitable for the deep drawing process. In addition to properties, aluminum discs also have lower price than other metal materials of similar features.
