Aluminum cans have the advantages of light weight, long shelf life, strong anti-counterfeiting, easy portability, and good recyclability, and their consumption is increasing year by year. Can sealing usually uses 5052 aluminum closure sheets, 3104 aluminum plate rolls, etc. The aluminum closing plates are usually stamped or formed into a specific shape that matches the contour of the can opening, tightly fitting the can mouth to prevent the contents from overflowing or leaking.

5052 aluminum sheets has good corrosion resistance, weldability, cold workability, and medium strength. Its surface is bright after coating, making it ideal for use as base caps for functional beverages. In addition, the 5052 aluminum sheets has a flat shape and can control the thickness more accurately, ensuring a thickness tolerance of ±0.005mm, thereby ensuring the stability of later processing.

3104 aluminum plate has excellent tensile strength and deep drawing performance, corrosion resistance, and elongation of up to 20%. In addition, it also has good processability, plasticity and stamping performance, as well as excellent surface quality and mechanical properties.
