Chemical Composition and Alloy Standards
The aluminum alloy base used for color coated foils is critical for achieving optimal flexibility, printability, and corrosion resistance. Standard alloys involved are aligned with ASTM B479 and EN 573 specifications.
| Element | Alloy 8011 (Typical) % | Alloy 3105 (Typical) % |
|---|---|---|
| Al (Aluminum) | Balance | Balance |
| Fe (Iron) | ≤1.0 | ≤0.5 |
| Si (Silicon) | ≤0.9 | ≤0.5 |
| Cu (Copper) | ≤0.03 | ≤0.3 |
| Mn (Manganese) | ≤0.4 | 0.8 – 1.3 |
| Mg (Magnesium) | ≤0.05 | ≤0.3 |
| Zn (Zinc) | ≤0.05 | ≤0.1 |
| Ti (Titanium) | ≤0.03 | ≤0.1 |
Alloy selection predominantly follows the prime requirements based on intended sheet flexibility, strength, and coat adhesion.
Tempering Conditions
The temper of the aluminum foil significantly influences mechanical performance as well as the surface quality for coating adherence.
| Temper | Description | Usage Application |
|---|---|---|
| O (Annealed) | Soft and fully annealed | Ideal for maximum flexibility and roll forming |
| H14 | Half hard (strain hardened) | Refers to medium strength with fair flexibility; excellent for decorative shaped products |
| H24 | Quarter hard with some strain hardening | Offers moderate strength and dimensional stability, generally recommended for planar decorative lamination without extensive deformation |
Commonly, the temper ranges from O to H14 for color coated foils, with O temper being predominant to maximize coating adherence and foldability.
Coating Technology and PE Layer Specifications
The polyethylene (PE) coating layer is applied via extrusion or solvent-based coating techniques, uniformly covering one or both foil surfaces. The coating provides:
- Vivid color retention
- Enhanced moisture and chemical resistance
- Improved barrier properties against contaminants
- Excellent adhesion to secondary substrates (e.g., adhesives, inks)
PE Coating Thickness: Generally in the range of 10μm – 50μm per sideSurface Finish: Matte or gloss options tailored to visual design demandsColor Fastness: Tested for durability against UV, moisture, and abrasion
Physical and Mechanical Properties
| Parameter | Typical Value | Test Standard |
|---|---|---|
| Thickness | 7 – 100 micrometers | ASTM B479 |
| Tensile Strength | 90 – 170 MPa | ASTM E8 |
| Elongation at Break | 8% - 18% | ASTM E8 |
| Density | 2.7 g/cm³ | ASTM B311 |
| Thermal Conductivity | ≈205 W/(m·K) | ASM Handbooks |
| Peel Strength of Coating | ≥3.0 N/cm (varies by thickness) | Internal protocol |
Generally, tensile strength is controlled via alloy tempering ensuring proper balance between material durability and ease of decorative forming.
