Will the long-term storage of the alloy aluminum sheets cause corrosion?

Alloy aluminum sheet is a commonly used machined aluminum sheet. After purchasing the alloy aluminum sheets, the customer is likely to stop the surface treatment, but will the long-term storage of the alloy aluminum sheets for sale cause corrosion? The following alloy aluminum plate manufacturer Haomei will analyze it for everyone.

There is no iron element or steel element in the alloy aluminum plate, so it will not corrode, but it is very easy to corrode when exposed to the air. The process of corrosion of aluminum alloy sheet is called oxidation. The oxidized aluminum oxide layer is thin. When the aluminum plate is oxidized, a hard oxide film will be formed on the surface, which will protect the aluminum plate from further oxidation. Corrosion of aluminum plate is actually due to oxidation, unless the surface alumina is removed, the aluminum plate will not further oxidize. Unlike rust which has a lumpy, red appearance, the aluminum oxide film does not easily fall off the metal surface. As for the factors that affect the oxidation rate of the aluminum alloy sheets, it actually mainly depends on the type of aluminum, the surface treatment and the natural environment around the aluminum. Generally speaking, the alloy aluminum plate is not easy to rust in the air, and an oxide film is formed on the surface to protect the alloy aluminum sheet.

Next, we will introduce the preservation method of alloy aluminum plate for sale. The preservation of alloy aluminum plates is quite easy to operate. When storing, we should pay attention to the packaged aluminum alloy sheet should be stored in a cool, ventilated and dry warehouse. When stacking aluminum sheets, we should stack them neatly, and the number of stacking layers should not be too high. Because the alloy aluminum plate is made of soft materials, if the accumulation time and weight are too large, the alloy aluminum sheets may be deformed under heavy pressure. Second, it is not appropriate to use steel wire ropes when using cranes to lift aluminum panels. If the aluminum alloy sheet is too thin, it is easy to be cracked and deformed by the four sides of the wire rope. In this case, we can use a cloth sling with a large stress area, and the wire rope can be hoisted with a special hook that is lifted in parallel on four sides. And these are the tips for the storage of aluminum alloy sheets.
