1100 aluminum sheet. It is used to process parts and components that need good formability and high corrosion resistance but do not require high strength, such as chemical products, food industrial devices and storage containers, sheet processing parts, deep drawing or spinning concave vessels, welding parts, heat exchangers, printed boards, nameplates, reflective devices.

3003 aluminum plate. It is used to process parts and components that require good formability, high corrosion resistance and weldability, or work that requires both these properties and higher strength than 1XXX series alloy, such as kitchenware, food and chemical product processing and storage devices, tanks and tanks for transporting liquid products, and various pressure vessels and pipes processed with thin plates.
