Aluminum bottle caps are widely used in the beverage, alcohol, food, medicine, pesticide, and cosmetics industries because of their good sealing effect and recyclability. Among the many aluminum bottle cap materials, 3104 aluminum sheet and 3105 aluminum sheet are two commonly used models. Today we will introduce them in detail:

3104 aluminum closure sheet belongs to a series of AL-Mn alloys. It is a deformed aluminum alloy with a tensile strength greater than or equal to 275MPA and an elongation of up to 20%. It has good deep drawing performance and is suitable for thinning, stretching and lightweighting to reduce the amount of material used. , bottle cap materials have strict requirements for each process, and MC Aluminum strictly controls each process so that the product has appropriate strength and formability.

3105 aluminum closure sheet belongs to a series of AL-Mn alloys. It has good anti-rust properties and good electrical conductivity. The aluminum content is 98%. Due to the addition of 0.3% copper element, the electrical conductivity can reach 41%; 3105 The aluminum sheet cannot be strengthened by heat treatment, so cold working methods are used to improve its mechanical properties: it has high plasticity in the annealed state, good plasticity during semi-cold work hardening, low plasticity during cold work hardening, good corrosion resistance, and good weldability. Poor cutting performance.

3104 3105 aluminum alloy bottle cap material specifications:

Thickness: 0.1-500mm

Width: 100-2650mm

Length: 500-16000mm

Application: wine bottle caps, beverage bottle caps, cosmetic caps, can caps, coated rolls, etc.

Aluminum bottle caps have a simple structure, strong adaptability, and good sealing effect. Compared with plastic bottle caps, they are not only superior in performance, but can also be mechanized and mass-produced. They are also low-cost, pollution-free, anti-theft, and can be recycled. . If special and advanced printing methods are used, not only can colorful patterns be printed, but the anti-counterfeiting effect is also very good.

MC Aluminum provides aluminum bottle cap materials 1060, 3104, 3105, 5052, 5182, and 8011. The company is equipped with an extra-long cleaning line and flat shears.
