1100 aluminum coil has the strongest mechanical strength in the highest alloy in 1000 series. Which containing at least 99% aluminium . It shows the properties of other 1 series alloys close to pure aluminum. Such as excellent ductility, corrosion resistance, weldability, processability, surface treatment, conductivity and heat transfer. Because of its excellent processing performance, 1100 aluminum coil can be well adapted to the application and is difficult to form. Therefore, 1100 aluminum alloy coil is often used for large refrigerator aluminum lining, HVAC, aluminum composite panels, building decoration, deep stamping parts, nameplate, etc.
