In order to increase the demand for deep drawing of aluminum for bottle caps, the wine industry is gradually increasing the use of aluminum for bottle caps. The working environment of the wine industry is very strict, which requires structural materials to have certain tensile strength, yield strength, elongation, pressure resistance, deep drawing and other properties. In addition, considering the structure and use environment of the wine industry, the wine bottle material also needs to have good food safety. Ordinary aluminum plates for bottle caps are difficult to meet the performance and safety of such strength bottle caps.
3105 aluminum plate belongs to a series of AL-Mn alloys, with good rust resistance and good electrical conductivity. The aluminum content is 98%. Since 0.3% of copper is added to it, the conductivity can reach 41%; 3105 aluminum plate cannot be strengthened by heat treatment, so cold processing methods are used to improve its mechanical properties: it has high plasticity in the annealed state, good plasticity during semi-cold hardening, low plasticity during cold hardening, good corrosion resistance, good weldability, and poor machinability.
The main thickness of 3105 bottle cap material products is 0.15-0.3mm, and the tempers are O, H12, H14, H16, etc.;
Advantages of Mingtai Aluminum 3105 aluminum plate for making bottle cap materials:
1. 3105 aluminum plate has good electrical conductivity. Since 0.3% copper element is added to it, the conductivity can reach 41%;
2. 3105 aluminum alloy has good anti-rust performance and is used in various bottle and can covers to achieve the effect of making the appearance of bottles and cans beautiful for a long time;
3. Good processing performance, novel product shape and long service life;
4. Strictly control the processing quality, texture, grain, composition, etc. of the product, and the product performance reaches the international advanced level.
