3104 Aluminum Plate for Can Lids

Durable & Formable Material for Packaging Industry Beverage can lids require materials that balance easy opening, sealing reliability, and mass production efficiency—and 3104 aluminum plate for can lids(a 3-series aluminum-manganese alloy) excels in all these aspects. As the core material for soda, beer, and energy drink can lids, it solves key pain points like poor formability or leakage for manufacturers. Henan Mingtai Aluminum Co, Ltd. (stock code: 601677), a leading aluminum processor with over 20 years of experience, produces high-quality 3104 aluminum plates that meet the strict standards of global canning brands.

1. Core Advantages of 3104 Aluminum Plate for Can Lids

3104 aluminum plate (with 1.0-1.5% manganese content) is tailored to can lid manufacturing, offering three unbeatable advantages:

Excellent Formability for Easy-Open Structures: Can lids need precise scores (for pull-tabs) and complex shapes (like rivets). 3104 aluminum plate in H19 temper has ultra-high ductility (elongation ≥3%) and uniform grain structure, allowing it to be stamped into lids with thin scores (0.08-0.12mm) without cracking. Even during high-speed stamping (600-800 lids per minute), it maintains consistent shape—critical for avoiding production delays. Mingtai’s 3104 aluminum plate has a thickness tolerance of ±0.005mm, ensuring every lid’s score depth is identical.

Superior Sealing Performance to Prevent Leakage: Beverage can lids must seal tightly to preserve freshness and avoid spills. 3104 aluminum plate’s surface is ultra-smooth (Ra ≤0.3μm), ensuring tight adhesion with rubber gaskets. Its moderate tensile strength (240-280 MPa) also allows the lid to fit snugly with the can body, resisting pressure changes (e.g., during transportation or refrigeration). Tests show that lids made from Mingtai’s 3104 aluminum plate have a leakage rate of ≤0.01%, far below industry standards.

Strong Corrosion Resistance for Beverage Compatibility: Canned beverages (especially acidic ones like soda or fruit juice) can erode metal over time. 3104 aluminum plate forms a dense oxide layer and is compatible with food-grade coatings—preventing chemical reactions with drinks. It passes 500-hour immersion tests in 5% citric acid solution with no corrosion, ensuring beverage safety and a 2-year shelf life.

2. Why 3104 Aluminum Plate Outperforms Alternatives for Can Lids

Compared to other materials like 5182 aluminum or steel, 3104 aluminum plate has unique advantages for can lids:

Better Formability Than 5182 Aluminum: 5182 aluminum has higher strength but lower ductility, making it prone to cracking during score processing. 3104 aluminum plate’s manganese content enhances formability, ideal for the intricate structures of can lids.

Lighter & Cheaper Than Steel: Steel lids are heavy (increasing transportation costs) and require anti-rust coatings. 3104 aluminum plate is 35% lighter than steel and naturally corrosion-resistant, reducing both material and processing costs by 15-20%.

More Cost-Effective Than 3004 Aluminum: 3004 aluminum has similar properties but is 10-15% more expensive. For standard beverage can lids, 3104 aluminum plate delivers the best balance of performance and cost.

3. Mingtai Aluminum: Reliable Supplier of 3104 Aluminum Plate for Can Lids

Mingtai’s production capabilities and quality control make it a trusted partner for can lid manufacturers worldwide:

Advanced Production Lines for High-Quality Plates: Mingtai owns the domestic first “1+4” hot rolling line, CVC 6-roller cold rolling mills, and tension bending straightening machines. These equipments produce 3104 aluminum plate with uniform thickness, flat surfaces, and no oil stains—critical for coating adhesion and stamping precision.

Strict Quality Control for Food Safety: With 600+ professional technical personnel, Mingtai conducts 100% inspections on 3104 aluminum plate, including chemical composition analysis (to ensure manganese content is 1.0-1.5%), mechanical property testing, and surface defect detection. All products comply with FDA 21 CFR 175.300 and EU 10/2011 food contact standards.

Eco-Friendly Production & Efficient Supply: Mingtai uses recycled aluminum (with harmless slag treatment) to produce 3104 aluminum plate, reducing carbon emissions by 18%—aligning with the packaging industry’s sustainability goals. Its 5 production bases and 6000+ employees enable flexible order fulfillment: from small batches (10 tons) to large-scale orders (10,000 tons), with delivery times as short as 3-30 days.

4. Application Cases of Mingtai’s 3104 Aluminum Plate for Can Lids

Mingtai’s 3104 aluminum plate has been widely used by global beverage brands:

Carbonated Drink Cans: Used for soda and beer can lids, withstanding internal pressure (up to 600 kPa) and preventing gas leakage.

Non-Carbonated Drink Cans: Ideal for juice, energy drink, and iced tea lids, resisting acidic corrosion and maintaining freshness.

Food Can Lids: Also suitable for small food cans (e.g., canned fruits), ensuring safe contact with food and easy opening.
