Aluminium sheet for pilproof caps
Aluminium sheet for pilproof caps 3105 belongs to the 3000 series aluminum-manganese alloy, it has good rust resistance and good deep-drawing effect. The strength, elongation and processing performance of the 3105 aluminum closure sheet material can meet the production process of automatic high-strength bottle caps, and there will be no creases or cracking phenomenon during processing. In addition, the 3105 aluminum sheet for pp cap material has a flat shape, no roll marks, and no oil spots, which is convenient for later printing and makes the pattern clear and recognizable. The producing characteristics of 3105 and 8011 aluminium sheet for pilproof caps are: 1, During smelting, casting and rolling, optimize the composition content of aluminum alloy in a small range: make the weight component content of Si account for 0.5-0.58% of the total weight of the alloy, and the weight component content of Fe account for the 0.6-0.68% of the total weight of the alloy, ...
