What is the corrosion resistance of Industrial assembly line aluminum profiles?

           Industrial assembly line aluminum profiles are characterized by their small specific gravity, easy processing, and high mechanical strength. Over the years, they have been widely used in building doors, windows, and curtain wall products. Aluminum is a relatively light and light metal with silvery white gloss.

           The corrosion resistance of industrial assembly line aluminum profiles generally has the following two characteristics. The higher the purity, the better the corrosion resistance. This is because pure aluminum plays a certain role in the air and oxygen, on the surface of aluminum It will produce a thin and very dense natural oxide film, which is faster and thicker than other metal oxide films. Although it prevents further corrosion of harmful gases and moisture in the air, it still protects effect.

            The mechanical strength of industrial assembly line aluminum profiles is generally relatively high, but its corrosion resistance is low. Although pure aluminum has good corrosion resistance, it has poor mechanical strength. This problem restricts the application of aluminum. Therefore, people have added appropriate amounts of magnesium, copper, zinc and other metals to aluminum to make Various types of aluminum alloy profiles greatly improve the mechanical strength of aluminum and the scope of application is greatly expanded, but its corrosion resistance will be worse than pure aluminum, so it may be corroded due to oxidation. At this time, we need to apply powder coating to protect the aluminum alloy profile.

            In addition to its relatively high corrosion resistance, industrial assembly line aluminum profiles also have many advantages such as a variety of colors and a good surface texture. Echo to adapt to different building styles.
