The aluminium sheet 1mm is a very common used aluminum product with alloy 1060, 3003, 5052 and 6061 grade. With the thickness of 1mm, this kind of aluminum sheet are widely used in industrial area. Aluminum will oxidize to form aluminum rust in a high temperature and high humidity environment for a long time. Aluminum rust is formed by the reaction of aluminum and oxygen-aluminum oxide, or aluminum oxide for short. The aluminum oxide trioxide has a compact structure and can be tightly attached to the surface of aluminum, which can effectively prevent the internal aluminum from being oxidized.
This is why aluminium sheet 1mm is often used as a raw material for waterproof tools. This oxide film is very thin, it is only as thick as 0.00001 mm. It is this film that forms a protective film. But his color is off-white or light yellow, not dirty like rust. The aluminum rust looks beautiful, and it makes people hard to feel the aluminum rust. Therefore, when using 1mm aluminum sheet products, it is not advisable to rub with hard objects to avoid damaging the oxide film protective layer. For high quality 1mm aluminium sheet product, the surface should be clear, neat, smooth, bright and clean, with even coloring and reflection, without obvious defects or damages such as wrinkles, bubbles, particles and impurities
After the customer receives the aluminium sheet 1mm, do not open the package directly after exposure to high temperature, because the surface of the aluminum sheet directly after the exposure will generate water vapor, which will increase the possibility of oxidation. Due to the temperature difference between different places is obvious. After getting the goods, they should be placed in a well-ventilated place for 2-3 days to allow the temperature difference between the inside and outside of the aluminum sheet to balance before opening the package.
