Pre-lubricated 3003 H24 aluminum foil is a specialized material developed by Haomei Aluminum for high-speed container forming. It uses 3003 aluminum alloy as the base material, undergoes H24 temper treatment, and is coated with a food-grade pre-lubricating coating. The thickness ranges from 0.03-0.15mm, and the width can be customized up to 1800mm. As a manufacturer specializing in aluminum foil exports for 15 years, we optimize alloy strength by precisely controlling the Mn content (1.0-1.5%), achieving a balance between 160-180MPa tensile strength and ≥3% elongation through H24 temper treatment. An online quantitative oiling process then forms a uniform lubricating layer of 150-400mg/m², providing customers with a ready-to-use forming solution.
The key technical indicators of pre-lubricated 3003 H24 aluminum foil strictly conform to international container production standards:
– Alloy composition:
Al≥98.0%, Mn 1.0-1.5%, Cu≤0.2%, Fe≤0.7%, Si≤0.6%, conforming to ASTM B209 and GB/T 3880.1 standards
– Mechanical properties:
Tensile strength 160-180MPa, yield strength 140-160MPa, elongation ≥3% (H24 state), ensuring molding stability
– Lubrication parameters:
Single-sided/double-sided optional, lubrication amount 150-400mg/m², using FDA/EFSA certified food-grade mineral oil or vegetable oil-based lubricant
– Surface quality:
Pinhole density ≤2/m², surface roughness Ra≤0.3μm, free from defects such as roller marks and streaks, ensuring smooth high-speed stamping
– Dimensional tolerances:
Thickness deviation ±3%, width deviation ±1mm, ensuring coil splicing accuracy and material utilization.
Technical advantages of pre-lubricated 3003 h24 aluminium foil including:
1. Lubrication Technology for 30% Improved Forming Efficiency
Pre-lubricated coating is a core competitive advantage. We employ slit-type extrusion oiling technology to form a uniform micron-level lubricating film on the foil surface, stabilizing the friction coefficient at 0.08-0.12, reducing frictional resistance by 60% compared to uncoated aluminum foil for food containers. In high-speed stamping line tests at a North American customer (200 cycles/minute), die life was extended by 40%, downtime for die changes was reduced by 50%, single-shift capacity increased by 32%, and unit production costs were directly reduced by USD 0.02-0.05/piece.
2. Performance Balance Design of 3003 H24 Alloy
In the 3003 alloy, Mn forms an Al6Mn strengthening phase, which, combined with incomplete annealing in the H24 state, achieves a precise balance between strength and plasticity. Aluminum foil in this state possesses sufficient hardness to maintain container shape (≥140MPa yield strength) and can maintain integrity during complex deep drawing (depth ≥50mm), making it particularly suitable for the production of irregularly shaped containers such as airline meal boxes and baking trays. Compared to alloy 8011, 3003 H24 exhibits 25% improved corrosion resistance, with aluminum migration controlled below 2mg/kg, meeting EU Regulation (EU) No 10/2011 standards.
3. Export-Grade Quality Control System
As a manufacturer with 85% of its products exported, we have established a full-process quality traceability system:
– Raw Material End: We use ≥99.7% high-purity aluminum ingots, with precise Mn element ratios and spectral analysis error ≤0.01%.
– Rolling End: A 20-roll Sendzimir mill controls thickness accuracy to ±2μm, and intermediate annealing temperature is controlled at 340-360℃ to ensure grain uniformity.
– Oiling End: Online infrared thickness gauges monitor oiling amount in real time, with a deviation ≤10mg/m², avoiding molding defects caused by uneven oil film.
– Testing End: Each roll undergoes pinhole, tensile, and corrosion resistance tests, accompanied by a COA certificate, meeting food contact standards in multiple countries such as FDA, LFGB, and GB 4806.9-2023.
