Why are frying pans made of aluminum alloy

Why are the frying pans made of aluminum alloy? At present, many frying pans on the market are made of aluminum alloy, but many people say that aluminum alloy pans are poisonous. What is going on? Is it not possible to buy a frying pan made of aluminum alloy? Let's take a look together!
The thermal conductivity of iron non-stick pan is not as good as aluminum non-stick pan, and the non-stick effect of iron non-stick pan is not as good as aluminum non-stick pan. In order to give consumers a better experience, the product will give priority to designing aluminum non-stick pans. In fact, this kind of aluminum is not pure aluminum, but aluminum alloy. It can make the amount of aluminum in food as little as possible, and it must be stated in the manual: Please do not use it after the coating has fallen off. In addition, the current advanced technology is to modify the coating to increase its wettability, so that it can adapt to more metal materials, rather than metal materials to adapt to the coating.
Is the aluminum alloy pot poisonous?
The aluminum alloy pot is used correctly, it is non-toxic.
Reason: The aluminum alloy pressure cooker must be anodized after forming to form a very dense oxide film on the surface of the aluminum alloy. Although the thickness of the film is not large, it is in the range of 10-20 microns, but its hardness is relatively high. As long as you use bamboo, wood or plastic rice shovel, the aluminum oxide film will not be damaged. If you use a metal spatula with flat and smooth ends, as long as it is not difficult to scratch, there will be no major problems, and will not cause aluminum to dissolve or fall. If the oxide film is destroyed, because aluminum is a very active element, it will be oxidized in the air immediately to form a hard aluminum oxide film, thereby protecting the aluminum body from continued oxidation and playing a good protective role. In this way, under normal circumstances, few aluminum ions escape. You can use it with confidence.
How to use aluminum pot is safer
1. There are two types of aluminum pots: refined aluminum and cast aluminum. The material is aluminum and aluminum alloy. The surface color can be divided into white and light yellow. White aluminum products are divided into casting and stamping. The surface of cast aluminum products has been car polished and mechanically polished, the surface is white, but the metal structure is loose, and there are certain casting defects; the surface of stamped aluminum products is washed white, polished and mechanically polished, and the surface is a natural oxide film, thin And uneven. Easily scratched or worn by machinery; yellow aluminum products are stamped products that have been anodized, and a light yellow artificial oxide film is formed on the surface. The film is thick and uniform. Under the action of strong alkali, the membrane will not be destroyed. , Light yellow aluminum products are the best.
2. If you use an aluminum pot for cooking, please do not empty the pot to ignite or ignite a small amount of water to dry the pot, otherwise it may cause water leakage at the bottom of the pot; the cooked rice and soup should be put into the bowl in time, not for a long time Put it in an aluminum tray to prevent the chemical reaction between aluminum and acid and alkaline substances to produce harmful substances. The material of the aluminum pan is relatively soft. When it is in a high temperature state, please be careful not to hit hard objects or put it in cold water. Cool to avoid deformation.
3. When cleaning the aluminum pot, do not use acidic alkaline cleaners to avoid chemical reactions and harmful substances to the body. Weak alkaline can be used. Do not use steel wire to brush the aluminum pot to avoid scratches. Use a sponge or a hundred pieces of clean cloth; when storing, pay attention that the surface will form a protective oxide film due to contact with air, which will darken the color of the pot, but it is not necessary to wipe it off, so as not to affect the service life of the pot.
