3003 aluminum disc circle for pressure cooker

3003 aluminum disc circle for pressure cooker is of aluminium manganese alloy, featured by good hardness, corrosion resistance and tensile strength. It’s stronger in hardness than 1060 but not so good in heat conductive, for its aluminum content is a little lower. This does not influence the cooking effect, for the conductivity gap between the two is really small. Instead, stronger hardness of the alloy helps to extend the service life of a cooker. The thickness of an aluminum circle for pressure cooker is bigger than that for ordinary cookers. Take Media pressure cooker liner for example. It adopts aluminum discs of 2mm thick, and the use of aerospace science and technology oxidation process not only makes the strength higher, but also greatly improves the wear resistance and non-stickiness. Aluminum pressure cookers are easy to clean, which proves to be a big problem with steel cookers, for the rice crust sticks to steel cookers so firmly that it’s really hard to remove it sometimes.

Pressure cooker aluminum circles can be of O, H12, H14, H22, H24 tempers, depending on the hardness you need. They are usually hot rolled to achieve the best integrated mechanical properties. Haomei 3003 aluminum disc circle for pressure cooker is of 1.0mm to 5.0mm thick, and 200mm to 600mm wide. The surface of the disc is free from marks, oil stains, oxidation traces or black spots. The edge of the circle is neat and clean. Haomei realizes quality control of its aluminum disc circles for pressure cooker in the following ways. First, strict control is carried out on the alloy, state and performance of the aluminum coil to ensure the accuracy and diversity of the discs provided. Second, the grain size and elongation of the aluminum coil must go through tests before the roll is fed into the production line. This ensures the excellent deep drawing and spinning performance of the disc, and effectively avoids the bad phenomena of wire drawing lines, ruffles and high ear rate that may appear in the later processing. Third, advanced and efficient production equipment ensures flatness, cleanness and neat edge of the circles. All these enable us to improve the aluminum circle production efficiency and material utilization, effectively shortens the production cycle, and provides customers with real-time convenience and detailed wafer classification.
