1060 aluminum cookee circle

1060 aluminum cookee circle is 0.01mm to 3mm thick and 100mm to 900mm round. Regular tempers include O, H18, H22 and H24. 1060 aluminum circle is an industrial pure aluminum whose aluminum content (mass fraction) is 99.60%. The circle hardness can not be strengthened by heat treatment. The surface of pure aluminum is silvery white, and its density decreases with the increase of purity or temperature. Aluminum circle 1060 features relatively simple production, mature technology and much cheaper prices. With good elongation and tensile strength, it can fully meet the conventional processing requirements (stamping, stretching) with high forming ability. It has high plasticity, corrosion resistance, conductivity and thermal conductivity, but its strength is low. It can be welded by gas welding, hydrogen atom welding and contact welding, and it is not easy to be brazed, and it is easy to bear all kinds of pressure processing, drawing and bending, proving to be a good material for cookees.

Aluminum cookee circle can be of many alloys in addition to 1060, such as 1050, 1070, 1100, 3003 and 5052. The main difference lies in end products. 1xxx circles are made into cookees like pots and kettles, but 3003 and 5005 aluminum circles are turned into higher end products, such as high pressure cookers, pizza trays and so on. Those for common cookware are mill finished, but sometimes anodizing and color coating are applied in production of 3003 and 5052 circles to improve the hardness and service life of cookware, which has stimulated the development of anodized aluminum circle and coated aluminum circle.
