Aluminum circle/disc/disk for non-stick utensil

May 28, 2021

An aluminum circle/disc/disk for non-stick utensil is a widely used utensil aluminum circle. The specifications of cookware aluminum discs usually overlap, but the non-stick utensil circles are usually small in diameter and thin in thickness, for they act as a layer of a utensil, which consists of a steel sheet, an aluminum sheet and a coating layer. And most non-stick utensils are actually pans that are shallow, small and light. The circle is also known as an alu disc, disk, wafer, round sheet etc., thus clients are forced to search long phrases as shown in the first sentence. But they are the same thing, a flat round aluminium sheet around 0.6mm to 3mm thick, and 80mm to 400mm big (diameter).

General alloys for non-stick utensil aluminum circles include 1050, 3003 and 8011. Aluminum has a much better heat conductivity than steel, thus a thin aluminum circle is added to the bottom of the steel. In this way the heat will be conducted to the food more evenly. Aluminium takes the heat quickly, and steel, whose conductivity is much smaller, spreads the heat to the food slowly to avoid burning. This is the structure of high-end non-stick pans and pots. Sometimes aluminium circles are made into non-stick utensil directly. These are usually hot rolled 3003 aluminum circles with a layer of anodized film and an extra non-stick coating. The thickness of such circles is bigger, for thin pans get food burned quickly.

Haomei produces aluminum circle/disc/disk for non-stick utensil of all specifications. At present, hot rolled circles include 1050, 3003, 5052 and 8011. The conventional process flow is: melting, casting and rolling, homogenizing annealing, sawing, milling, heating, hot rolling, cold rolling, punching, finished annealing, and packaging. Long time homogenization annealing is employed to avoid segregation of the circle material resulting from the large size of the fusion cast ingot and the slow cooling rate. Before hot rolling, the ingot needs to be evenly heated to about 500°C again, and then hot rolling is started. The process above enables Haomei to supply top quality circles for clients.
