4. Annealing: Softening the aluminum for ductility.
5. Lubrication and Rolling: Further reducing thickness with improved surface finish.
6. Final Annealing: Adjusting properties for optimal performance.
7. Slitting and Cutting: Cutting to the desired width.
8. Quality Control: Ensuring all foils meet our stringent requirements.
9. Packaging and Distribution: Preparing the foil for delivery to our valued customers.

Comparison: 8021 Aluminum Foil vs. 8011 Aluminum Foil

While both 8021 and 8011 aluminum foils are popular, they serve different needs:

• Alloy Composition: 8021 contains about 1% other elements, mainly iron and silicon, similar to 8011.
• Flexibility and Softness: 8011 is softer and more elastic, making it ideal for flexible applications.
• Strength and Durability: 8021 has higher tensile strength and better elongation, suitable for robust applications.
• Corrosion Resistance: Both have good resistance, but 8021 is preferred for corrosive environments.
• Barrier Properties: 8021 excels in moisture and gas barrier properties, crucial for pharmaceutical packaging.
• Thermal Conductivity: 8021 has good conductivity, but 8011 is often chosen for culinary uses due to its heat transfer properties.
• Applications: 8021 is favored for pharmaceutical blister packaging, while 8011 is common in household and culinary applications.
