Processing and Handling of 1050 Aluminum Circles for Cookware
The journey of a 1050 aluminum circle into a finished cookware item involves several key manufacturing steps. Its excellent formability allows for efficient deep drawing, where the flat disc is pressed into a mold to create the initial pot or pan shape, or spinning, where it’s rotated at high speed against a tool to form round profiles like kettles. Following forming, cookware may undergo surface treatments such as polishing, brushing, or sandblasting.
Finally, it’s prepared for the application of non-stick coatings, ceramic coatings, or anodizing to enhance durability, aesthetics, and cooking performance. The high purity of 1050 aluminum ensures these coatings adhere well and perform optimally.
