The elongation, internal structure, and grain size of the hot rolled DC aluminium sheet circle material are superior to those of cold rolled aluminum circle products. Now aluminum deep-processed products are usually formed by deep-drawing aluminum circles through stamping equipment or spinning equipment. The extension of aluminum discs has higher requirements. At the same time, the current high-end lamps and cookware will undergo surface treatment after being processed and formed. The hot-rolled aluminum circle sheet not only have high elongation, but also have good anodizing effects, which are especially suitable for this type of high level product application use.
The aluminium sheet circle have wide application in our daily life, such as cooking utensils, containers, lamp covers, road signs and traffic signs. Aluminum circles for cookware are mainly hot-rolled aluminum sheet coil material, with good grain size control, suitable for deep-drawing and spinning. Aluminum circles for stamping and drawing for lamps have advantages of high surface finish, no scratches and high elongation. The aluminum circle sheet for traffic signs belong to the bending discs, which are processed by aluminum sheet through round bending equipment, and are suitable for use in various traffic signs, road signs and other industries.
For processing cookware is the biggest application of aluminium sheet circle. Most of the cooking utensils made of aluminum sheet circle are oxidized, but some are sprayed, which requires high performance of aluminum plate circle. 1000 series and 3000 series of aluminum sheet are used for making cookware. Customers who make woks, frying pans and burning pans use double-sided spraying. They should use Teflon fluorocarbon paint to spray the surface. Some use hot-rolled 3003 O-state aluminum circle sheet or 1100 aluminium circle sheet in O state, but the latter is easy to deform after heating.
