Overview
3104 Aluminum coil for the can and bottle cap is a high-performance packaging material belonging to the 3-series Al-Mn alloy, specially optimized for the production of beverage cans, food cans and bottle caps. It undergoes precision rolling, annealing and other processes to form a coil product with uniform thickness and excellent surface quality. It is mainly supplied in H19 ultra-hard temper, featuring good deep drawability and corrosion resistance, which can perfectly adapt to the high-speed stamping, thinning and ironing processes in can and cap manufacturing. As the mainstream material for can bodies and caps in the global packaging industry, it has the advantages of lightweight, non-toxicity, tastelessness and recyclability, fully complying with international food packaging safety standards. It effectively reduces material consumption and production costs while ensuring the airtightness and structural stability of packages, and is widely recognized by major can-making and packaging enterprises worldwide.
Specification
Alloy: 3104
Temper: H19
Thickness: 0.208mm-0.36mm
Width: 600mm-2400mm
Feature
1.Superior Corrosion Resistance: The corrosion resistance of 3104 aluminum coil is good, effectively resisting corrosion from beverages, food acids and alkalis, and no pre-treatment is required for direct contact with food.
2.High Surface Quality: The surface is clean, smooth and free of defects, with good printability and coating adhesion, which can meet the requirements of product labeling and decorative printing on can and cap surfaces.
3.Lightweight & High Strength: Density is2.73 g/cm³, with tensile strength of 270–320 MPa (H19 state).
4.Recyclability: Food Safety & Environmental Friendliness: The alloy composition is stable, non-toxic and tasteless, in line with global food packaging safety standards; the aluminum base material is 100% recyclable, aligning with global sustainability trends.
5.Cost-Effective: Lower cost than 5000-series alloys (e.g., 5052) while maintaining performance.
