The range of metal materials used for cooking utensils is very narrow, because cooking utensils need good thermal conductivity and stable chemical properties, otherwise the taste of food will change. Many metals have good thermal conductivity, but their chemical properties are too unstable to be used for food processing. However, in some cases, aluminum circle for cookware bottom can be made of very unstable metal materials and then plated with other stable materials. Aluminum is a metal with excellent thermal conductivity. It will not rust and is resistant to many forms of corrosion. It is a commonly used metal for cooking utensils!


 
Aluminum generally exists in the form of drawing, die casting or anodizing. Drawn aluminum is formed by rotary stamping. Because this kind of metal is soft, it is generally made into aluminum alloy with magnesium, copper or bronze to increase strength. aluminum circle for cookware bottom is widely used in baking boards, fruit juice boards, cake muffin baking pans, soup pans, steam pans, pasta pans, and even frying pans. Die cast ones are often thicker than stretched ones, making them more suitable for soup pots, Dutch pots and heavy baking pans. The thermal conductivity of aluminum die-casting products is lower than that of drawing pots because of the microscopic performance pores produced in the die-casting process. Anodized aluminum naturally contains a layer of aluminum oxide formed by electronic processing, which is hard and not easy to react with other substances. This process is often used to make juice pots, stews, roasters and Dutch roasters.
