[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 more susceptible to corrosion when exposed to hydrochloric acid and alkaline substances.
Aluminum plates made from 99% pure aluminum offer excellent corrosion resistance, but they tend to have lower mechanical strength. To improve strength and other 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 joining. However, for thicker sections—over 1.5mm—welding is preferred. It's important to handle and transport the sheets carefully to prevent scratches and damage to the surface, which can affect both appearance and performance. Proper care during processing ensures the longevity and quality of the final product.
