5182 aluminum alloy belongs to Al-Mg alloy which is not heat-treated. The alloy has good corrosion resistance, processing property, good strength, elongation, deep drawing performance and welding performance. It is widely used to process the cover of the can, the shutter, car body plate, steering wheel, reinforcement, bracket and other parts. 5182 aluminum coil sheet for closure caps are the typical application of 5182 aluminum alloy which have high comprehensive performance requirements.
And the aluminum packaging are usually used in modern society, due to the environmental feature, aluminum can be used for the package bottle body and bottle caps. Aluminum manganese alloy 3004 is used on the bottle can body in order to get better deep drawing performance and strength, while the closure caps and can ring require high strength, the aluminum magnesium alloy 5182 aluminum is used. In recent years, the production of aluminum cans bottles has been increasing year by year. 5182 aluminum closure sheet for caps have many advantages, such as light weight, good airtight and difficult to break. Aluminum closure caps materials are so popular because aluminum itself has good oxidation resistance, the cap can be sprayed with color to maintain more than 15 years of non-decolorizing, non-corrosive.
