8011H16 aluminum alloy bottle cap material
Aluminium and aluminium alloy cap material is a new type of bottle cap sealing material, not only has the characteristics of beautiful appearance and easy to open, and to prevent counterfeit goods function, therefore, at home and abroad have been widely used in beverage bottles, wine bottles, cosmetic bottles, bottles and other sealing packaging. 8011 aluminum alloy as the main anti-theft cover material, in addition to a good deep drawing properties, low earing rate, also requires after the cap process after baking, has a certain strength. At present, plate production of aluminum alloy 8011 bottle cap material H16 state, punching the height of 50mm above the high cap, lower thermal stability after baking sheet, the difference of tensile strength, earing rate instability, resulting in punching cap of the low rate of finished products, the forming of the poor. Therefore, the optimization of machining the existing production process, the various performance indicators is of great significance to a higher level. The main alloy elements of 1 test methods of 8011 aluminum alloy is Fe, Si, and others are trace impurity elements. Experiments using DC semi continuous casting, production specifications for 480 * 1630mm aluminum alloy flat ingot. The specific process is: smelting, casting, hot rolling, cold rolling, are heat - intermediate annealing, cold rolling, straightening, longitudinal or cross cutting and packing. Content and ratio of main control of melting and casting of alloy elements, the heating temperature are heat by 500 - 5 DEG C, the heat preservation time is not less than 20h. Ingot by "1+4" hot rolling billet rolling, control of hot finish rolling temperature less than 280 DEG C. Effect of content and ratio of main elements in alloy test study on properties of alloy;Haomei supplies a range of quality alloys (AA8011, AA3105) and tempers (H14, H16, H24, H26) for a wide variety of closure applications in packaging industries, such as Beverage, Food, Pharmaceutical/Medical, Pesticide, Health Care, etc.
