[China Aluminum Network] Aluminum plates come in various types, primarily divided into pure aluminum plates and aluminum alloy plates. The surface of an aluminum plate naturally forms a thin layer of aluminum oxide, which acts as a protective barrier against further corrosion from the environment. While aluminum is resistant to nitric acid, it is vulnerable to corrosion when exposed to hydrochloric acid and strong alkalis.
Aluminum plates made from 99% pure aluminum offer excellent corrosion resistance but tend to have lower mechanical strength. To enhance its properties, small amounts of elements like copper, silicon, magnesium, and zinc are added to create aluminum alloys. In everyday applications, we commonly use either pure aluminum plates or annealed aluminum alloy plates.
When manufacturing air ducts or components using aluminum plates, if the thickness is less than 1.5mm, it's typical to use bite joints for assembly. However, for thicker sections (over 1.5mm), welding is the preferred method. During transportation and processing, it's crucial to protect the surface of the aluminum sheets to prevent scratches and damage that could affect both appearance and performance.
