Tempering and Mechanical Properties
The H14 temper represents strain-hardened (quarter hard) aluminum:
| Property | Typical Values |
|---|---|
| Tensile Strength (MPa) | 175–220 |
| Yield Strength (MPa) | ~130–160 |
| Elongation (%) | > 3 |
| Hardness (HV) | 60–75 |
| Density (g/cm³) | 2.7 |
These mechanical characteristics offer a balanced compromise between ductility and strength, suited for both structural integrity and complex forming operations.
PE Painted Coating Attributes
- Polyester Coating: Renowned for its good weather resistance, color retention, and excellent printability.
- Blue Color: Offers specific visual appeal for architecture and branding.
- Durable Layers: Applied via continuous coating lines where cleaning, pretreatment, primer, PE painting, and top-coating layers ensure adhesion, corrosion protection, and wear resistance across applications.
Implementation Standards
Coated aluminum coils must adhere to several standards that govern their metallurgical, mechanical, and coating attributes, for assured quality and interoperability:
- Aluminum Alloy Standard: ASTM B209 / GB 5009 aluminum sheet and coil specifications
- Temper and Mechanical Standard: ASTM B547 – Surface inspection standard, ASTM B209 quality assurance
- Paint Coating Quality: ISO 2813 (Gloss Measurement), AAMA 2605 for architectural applicative painting durability; ASTM D3363 for pencil hardness measurement
- Surface Pretreatment: Compliance with RoHS for environmental safety; use of chromate/passive-free pretreatment in some cases
Functional Advantages
- Corrosion Resistance: Enhanced by the A3003 alloy composition and PE polyester coating, protecting materials against oxidation in humid, industrial, or coastal regions.
- Flexibility & Formability: H14 temper allows easy roll forming, bending, or pressing without compromising material strength.
