3003 aluminum disc is the ideal material for cookware use, which has higher performance than 1000 series aluminum discs. The shrinkage of the 3003 aluminum alloy has a decisive influence on the quality of the manufacture of the cookware. It affects the formation of cracks and changes in size. The 3003 aluminum-manganese alloy has strong shaping ability and moderate hardness, and can stabilize its dimensional change.
3003 aluminum discs belong to the aluminum-manganese alloys, in the manufacture of cookware, 3003 aluminum-manganese alloys do not have cracks, mainly because their shrinkage stress is far beyond the bonding force between metal grains, and each surface maintains remarkable metallic luster. The composition properties of the aluminum-manganese alloy directly affect the gas-tight process performance of the alloy. If the initial solidification range of the alloy is smaller, the tendency of looseness between the molecules is smaller, and the pores capable of maintaining gas evolution will be smaller, the degree of airtightness of the alloy will be higher.
It is precisely because the 3003 aluminum-manganese disc can fuse the characteristics of the elements in the alloy in the manufacture of the cookware to achieve better process performance, so that the 3003 aluminium disc can be the best choice for the manufacture of the cookware in many metal materials.
