As the global packaging industry shifts toward lightweight and eco-friendly solutions, 3105 aluminum for closure caps is emerging as a game-changer for beverages, cosmetics, and pharmaceuticals. This aluminum-manganese alloy excels in formability and corrosion resistance, meeting stringent demands for seal integrity and safety while offering end-to-end customization for international brands.
As part of the 3xxx aluminum-manganese series, 3105 aluminum stands out for its high plasticity, low earing rate, and superior deep-drawing performance. In its annealed state, the material withstands complex deformation—making it ideal for multi-stage stretching processes like roll-on pilfer-proof (ROPP) caps. Its flawlessly smooth surface, free of roller marks or oil stains, also ensures pristine printing quality for crisp branding.
Beyond performance, 3105 aluminum meets food-safety standards. With controlled smelting and rolling, it achieves pharmaceutical-grade purity, eliminating risks of metal ion migration—a critical feature for wine, spirits, and medicine bottle seals.
Mingtai Aluminum tailors 3105 aluminum for closure caps to global needs, offering:
– Thin gauges (0.15–0.27mm): Optimized for deep-drawn caps.
– Extra-wide coils: Compatible with high-speed automated lines.
– Custom tempers (H16/H18) & finishes: Balanced strength and formability.
The company’s rapid-response system handles non-standard specs, leveraging precision slitting and cleaning lines to produce coils with tighter-than-industry tolerances—reducing waste in downstream cap manufacturing.
