The <strong>hot rolled 1050 o' aluminium circle for cookware</strong> is the most frequently applied specification in the cookware industry. In addition to cookware, aviation, automobile, ship and other transportation manufacturing industries also applies aluminum circle sheets.<br></p>

Regular alloys for cookware include 1050, 1070, 1100, 1060, 3003 and 5052 etc.. Main thicknesses are 0.3mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.2mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, 4mm, 5mm, 6mm, 8mm and 10mm. The diameter ranges from 100mm to 1200mm. The <strong>characteristics of 1050 aluminum circle sheet</strong> include light weight, strong corrosion resistance and good elongation. 1050 circle contains 99.5% aluminium that is known for low density and hardness. An aluminum circle weighs only one third of a steel disc of the same size. Though aluminum is not the lightest of all regular metals, it has the best integrated properties. Magnesium, for instance, boasts a smaller density then aluminum, but not so tensile as the latter, which means it breaks easily under tearing forces, not to mention forces from deep drawing or spinning. A strong corrosion resistance of aluminum does not indicate it has no reaction with other elements, but that it reacts to oxygen swiftly and generates oxide aluminum that is further resistant to most corrosive chemicals. This layer, however, is so thin that it needs to be thickened and improved by surface treatments like anodizing or color coating, during which anodized and <strong>pre-painted aluminum circle</strong> discs are developed.</p>

The peculiarities of a hot rolled 1050 o' aluminium circle for cookware fall on rolling method and temper. Tempers of
aluminum products incorporate O, H12, H14, 16, H22, H24, H26, H18, H32, H34, H36, H111, H112 and so on, among which O stands for the full annealing state, namely, the softest state of all. This suggests outstanding tensile strength and further processing properties (deep drawing, spinning). “Hot rolled” instructs the rolling method of the circle. Different from cold rolling, hot rolling makes thick aluminum bulks into thin pieces at high temperatures, transforming structures and improving mechanical properties of finished products. Therefore, hot rolled aluminum circles withstand stronger exterior forces and display better deep drawing properties.</p>
