Aluminum Alloy 1100 Aluminum Foil Air Conditioner Heat Sink Material (0.1–0.15 mm | Custom Width | Hydrophobic Coating)

Introduction 

The 1100 hydrophobic-coated aluminum foil for air conditioner heat sink fins (0.1–0.15 mm thickness, 200–1650 mm customizable width, nano-hydrophobic blue/gold coating) is the global HVAC industry’s most cost-effective and high-performance material for high-efficiency, odor-free evaporator and condenser fins.

• Alloy 1100: purity ≥ 99.0 %, best thermal conductivity (237 W/m·K), excellent formability.
• Hydrophobic coating: contact angle > 120°, 3000 h salt-spray, condensate rolls off instantly → no water film, no bacteria.
• Meets RoHS, REACH, JIS H 4160, ASHRAE 90.1 energy efficiency standards. Result: fins that boost heat transfer by up to 25 %, permanently prevent mold & odor, and extend AC life to 20+ years.
