During the drawing process, crystalline directionality can cause uneven rim heights ("earing"). Shanghai Friend Metals controls cold rolling reduction ratios and intermediate annealing temperatures to maintain 45° planar anisotropy, keeping earing values strictly under 1.5%. This reduces trim scrap on customer filling lines.
Coils are coated using high-speed roll applicators with thermosetting organosol, modified epoxy, or cutting-edge BPA-NI (Non-Intent) acrylic lacquers. Formulated to withstand 121°C retort sterilization for 30 minutes without micro-cracking, blistering, or loss of adhesion.
Utilizing high-precision rotary slitting lines with automated laser guidance, our coils feature edge wave freedom, zero burr height (< 0.01mm), and custom slit widths down to 20mm with a tolerance of ±0.05mm, ensuring smooth feeding into high-speed stamping presses.
How Shanghai Friend Metals leverages integrated industrial clusters, advanced mill technology, and Shanghai port logistics to optimize cost, lead times, and global reliability.
By sourcing raw primary aluminium ingots directly from low-carbon hydroelectric smelting facilities and partnering with top-tier continuous hot-rolling mills, we guarantee metal purity (99.7%+ Al) and consistent ingot-to-coil metallurgy.
Located in Shanghai—the world's largest container throughput hub—our warehouse facilities execute customs documentation, ocean container loading, and port delivery within 72 hours of production completion, reducing total transit cycles by up to 10 days.
Every coil batch is subjected to rigorous lab testing: pinhole optical scanning, enamel rater electrical conductivity testing (< 2mA target), solvent rub resistance (MEK test > 100 double rubs), and double-seam tear-down validation.
Tailoring aluminium coil mechanical tolerances, surface lacquers, and dimensions to regional market standards across North America, Europe, Asia-Pacific, and the Middle East.
In North America, high-capacity canning lines operate at speeds exceeding 1,200 cans per minute. We supply 3104-H19 body stock and 5182-H48 shell stock engineered for 202 SOT ends. Material tolerances are kept within ±0.005mm to prevent jams during necking and double-seaming, supporting both standard 12oz (355ml) and sleek 12oz formats.
European Union directives mandate strict compliance regarding chemical migration. Our 8011-O and 5052-H32 coils destined for European fillers feature advance BPA-NI (Non-Intent) lacquer systems, ideal for infant formula powder lids, peel-off foil membranes, and nitrogen-flushed coffee containers requiring barrier integrity.
Hot, humid, and coastal environments accelerate oxidation in stored metal packaging. Coils supplied to MEA and tropical Southeast Asia are treated with anti-corrosion chrome-free passivation layers and heavy-duty external varnish to withstand sea freight condensation and prolonged ambient storage without surface degradation.
Beyond packaging, our 5052 and 3004 coils are cut to custom widths for automotive thermal insulation panels, battery pack enclosures, and HVAC heat exchangers, leveraging high thermal conductivity, low density, and high deep-drawing ductility.
Pioneering ultra-thin gauge reduction, closed-loop circular aluminium recycling, and AI-driven dynamic surface quality monitoring.
Research is accelerating the transition of can end shell stock from 0.208mm down to 0.180mm without sacrificing buckle strength. By refining micro-alloying elements (controlling Fe:Si ratios and Mg distribution), Shanghai Friend Metals is pushing the boundary of material efficiency.
In accordance with global circular economy goals, our metallurgical processes are expanding the incorporation of Post-Consumer Recycled (PCR) scrap up to 85% in coil substrate production, reducing embodied carbon by up to 95% compared to primary smelting.
Our slitting and lacquering lines feature high-definition CCD camera inspection system scanning 100% of coil surface area at speeds up to 400m/min. Pinholes, scratches, and lacquer voids are flagged and removed automatically.
Ensuring complete peace of mind with food-contact certification, comprehensive mill test reports, and ocean freight moisture protection.
All internal coatings applied to our aluminium coils comply directly with FDA 21 CFR 175.300 (USA), EU Regulation 1935/2004, Commission Regulation (EU) No 10/2011, and China's GB 4806.10 food safety standards. Heavy metal content satisfies RoHS and REACH specifications.
Coils are packaged for long-haul sea transportation: eye-to-sky or eye-to-wall orientation, wrapped in VCI anti-rust film, shielded with corrugated hardboard edge protectors, secured on heat-treated ISPM-15 wooden pallets, and loaded with silica gel desiccant packs inside sealed containers.
Our packaging application engineers assist overseas customers with seamer tool setup, double-seam teardown evaluation (thickness, overlap, countersink depth, seam gap), and sample trial lot validation prior to full container production.
