The 1100 aluminum coil, which contains at least 99% to, is the heaviest 1000 series of alloys, and thus the most mechanically strong alloy in the series. Similarly, the 1100 aluminum alloy coil exhibits other properties that are close to pure aluminum series alloys. Such as Excellent ductility, machinability, corrosion resistance, weldability, surface finish, electrical conductivity and heat transfer. Due to its excellent machinability, 1100 aluminum coils are well suited for difficult-to-form applications. Therefore, 1100 aluminum Alloy coils are usually used as aluminum linings for large refrigerators, HVAC, aluminum-plastic panels, building decoration, deep-drawing parts, nameplates, etc.
