Aluminum alloy pots are light and durable, because there is no "rust" problem, and they look more "beautiful" than iron pots. Its biggest feature is fast and uniform heat conduction. In the past, the common aluminum wok in the market was used to cook sour, alkaline or salty food due to technological reasons, and the aluminum in the wok would dissolve out the contaminated food, which would have adverse effects on the human body. At present, aluminum alloy pots on the market have been specially treated, which makes them safer to use, but at the same time, we should also pay attention to choosing aluminum alloy pots with big brands, and the quality will be more guaranteed.
Because the hardness of aluminum alloy is relatively low, it can be made into more shapes and colors under the processes of die casting, casting and drawing. Used for cooking clear soup dishes, desserts, etc. Aluminum alloy pot can be used for multiple purposes, and it rarely changes color because of the pot itself.
Stainless steel pot, with its beautiful appearance, exquisite structure, durability, purity and pollution-free, has the characteristics of "physical non-stick" and "less oil smoke", and has quickly become the new favorite of modern kitchen utensils market. However, due to the heavy pot body of pure stainless steel pot and uneven heat conduction, stainless steel pot, which is popular in the market, mostly adopts "multi-layer composite" technology to improve the technology of stainless steel pot. It is because this kind of steel contains a certain amount of chromium alloy elements, which can form a solid oxide film (passivation film) insoluble in some media on the surface of the steel, so that the metal is isolated from the external media without chemical action.
This kind of multi-layer pot (usually three or five layers, as can be seen from the product description) has the characteristics of durability, good heat conduction, good heat transfer and insulation effect, easy cleaning and so on, and with the gradual expansion of the market, the price is gradually close to the people, which is favored by ordinary families. Take the three-story stainless steel pot as an example. The third layer consists of 304 stainless steel, pure aluminum sandwich and 430 stainless steel (from inside to outside). Summarizing the comparison of the two kinds of pots, I personally suggest choosing stainless steel pot.
