The 1100 aluminum alloy in H14 temper undergoes strain hardening via cold rolling, creating a partially hard and strain-hardened condition. The term H14 denotes a proprietary term for "strain hardened to half hard":
- Aluminum billet is cast and rolled to the required gauge.
- Cold rolled and controlled to achieve 12–18% elongation reduction.
- Relaxation annealing is avoided to retain cold work strength.
- Causes moderate increase in tensile and yield strength with retained flexibility.
- Hardness and workability reminisce important for precision application surfaces such as solar mirrors.
Applications
- Solar Energy Heliostats & Mirrors: For concentrating solar power reflecting mirrors with high efficiency and durability.
- Lighting Fixtures: Manufacture of reflective light recycling surfaces to enhance light output.
- Architectural Decoration: Indoor/outdoor surface treatments with reflective aesthetics and corrosion resistance.
- Electronic Device Casings: Housing requiring good thermal and electrical performance combined with reflective finishing.
- Printing & Signage Substrates: Mirror-like background for high-impact visuals and back-lit signage.
Handling and Storage Recommendations
- Store the coil in a clean, dry, and ventilated warehouse to prevent moisture fallout and micro-corrosion focus.
- Avoid contact with abrasive or corrosive compounds during transportation or handling.
- Use protective film or packaging when moving post-finishing to ensure surface integrity.
- Design twisting or fabricate under temperature control to maintain the mirror reflective surface quality.
