Aluminum Circle

Aluminum Circle is a circular flat product obtained by circular sawing or shearing (i.e.: diameter over 700 mm), or by blanking (i.e.: diameter less than 700 mm) of a flat rolled product with a uniform thickness over 0.5 mm. Its stock is usually the cold rolled sheet in coil or rectangular sheet in small size, and both DC and CC materials are available upon request. It is subsequently formed or drawn for applications of kitchenware and containers.
