An aluminum alloy circle plate can be of 1050, 1060, 1070, 1100, 3003 or 5052 grade. Among these 5052 is the strongest in hardness and corrosion resistance. The basic process falls on two types: cold rolling and hot rolling. The latter makes circles with better tensile strength and resistance to deformation. Take hot rolled 1050 o' aluminium circle for cookware for example. It displays high plasticity and low deformation resistance, which greatly reduce the energy consumption of metal deformation in further process. In other words, adopting hot rolled aluminum discs to make cookware helps to reduce energy consumption. However, the thickness and size of hot-rolled aluminum products are difficult to control, and the control accuracy is relatively poor. Therefore, hot-rolled plates are generally used as billets for cold rolling.

 

Other industrial round aluminum plate products of 1000 series have similar mechanical and chemical performances to 1050 circle, either cold rolled or hot rolled. Among them, 1100 is the hardest and most corrosion resistant, because it contains the highest share of alloy metals. None of these, however, is regarded as an alloy aluminum circle plate strictly in China, for they are known as pure aluminium circles. Alloyed ones include 3003, 3004, 3005, 5052 and even 6061. Except 6061, the other four are known as anti-corrosion aluminum circle plates, as they contain manganese and magnesium respectively, both of which show excellent corrosion resistance. Alloy circle plates are stronger and more fatigue resistant. 6061 aluminium is rarely made into circles, for it's too hard.

 

Generally speaking, 1xxx circles are applied in common cookware and lighting, while 3xxx and 5xxx in high-end products of similar industries. Thickness ranges from 0.4mm to 6mm, and diameter from 100mm to 1250mm. If you have special requirements, anodizing and color coating is available. Customization of specifications is acceptable.
