According to the related statistics, about half of the world's cooking utensils are made of aluminum. The heat efficiency of aluminum utensils is as high as 93%, while stainless steel and cast iron are only 1/3 of aluminum.The aluminum circles for utensils will greatly increase the physical and chemical characteristics of the cooking utensils, such as electrical conductivity, thermal conductivity, heat resistance,etc.The production process of cooking utensils mainly includes blanking, deep drawing, flushing, bottoming and cleaning. In the blanking process, the choice of metal is very important. According to the kinds of utensils, we need to choose different aluminum grades and types.For example, aluminum discs stamping is relatively soft and some other metal elements like magnesium, copper, and bronze are needed to add its strength. Die-casting aluminum discs is often thicker than aluminum discs stamping.This structure is more suitable for thick soup pots. Due to the extremely small porosity of die-cast aluminum, its thermal conductivity is much lower than that of aluminum circle stamping.In addition to excellent heat efficiency, aluminum disc circle will not rust, and can maintain resistance to a variety of corrosion. With an oxide layer, anodized aluminum discs is more difficult to react with other substances.At present, most of the cookers on the market are manganese-
