Aluminium sheet for bottle cap

Haomei aluminium sheet for bottle cap covers alloys of 1060, 3104, 3105, 5052 and 8011. All these bottle cap aluminum sheets can be made by direct casting and continuous casting. Aluminum bottle caps have a large stretch length, so materials with better elongation must be selected. The alloys above have proper elongation, good corrosion resistance, good processing performance, and can be smelted and processed into alloys of different hardness according to different application requirements. In addition, Haomei precision integrated plate convexity control system greatly improves the quality of its aluminum bottle cap sheets. It would be a best choice for you to purchase Haomei aluminum sheets for making bottle caps.
