Why Use 1100 HVAC Aluminum Foil？

Material Application: HVAC

Product: 1100 aluminum foil

Project Details:

In high-efficiency HVAC systems, 1100 HVAC aluminum foil is becoming the mainstream industry choice due to its unique physical properties and cost advantages. As a representative of industrial pure aluminum, 1100 aluminum foil contains 99% aluminum. Its non-heat-treatable strengthening characteristic ensures lightweight performance while maintaining excellent thermal conductivity, corrosion resistance, and workability. Compared to 3003 aluminum alloy, 1100 foil eliminates the need for manganese additives, reducing costs by approximately 15%, while offering 20% higher thermal conductivity—a critical feature for rapid heat exchange in air conditioner evaporators and condensers.  

Superior Heat Transfer and Energy Efficiency  

The core advantage of 1100 HVAC aluminum foil lies in its exceptional thermal conductivity. Experimental data shows a thermal conductivity of 222 W/(m·K), over three times higher than traditional galvanized steel. In HVAC heat exchangers, using 0.1mm-thick 1100 foil for fins improves heat exchange efficiency by 18% and reduces system energy consumption by 12%. For example, a commercial complex project in Guangzhou achieved a 23% reduction in air conditioning electricity usage after material replacement. Additionally, the oxide layer on 1100 foil is only 0.01mm thick but forms a dense protective barrier, withstanding 5,000 hours in 90% humidity salt spray environments without corrosion, significantly extending equipment lifespan.  

Lightweight Design and Installation Convenience  

With a density of just 2.7 g/cm³—65% lighter than copper—1100 foil is particularly advantageous in ventilation duct systems. Using 0.08mm-thick foil composite ducts reduces weight by 40% compared to galvanized steel pipes and lowers transportation costs by 30%. In residential fresh air retrofits, φ100mm aluminum foil ducts can be concealed within ceilings, cutting installation time by 50%, with teams laying up to 300 linear meters per day. The foil ducts also feature a bending radius of 1.5 times the diameter, adapting seamlessly to complex structures, minimizing joints, and keeping air leakage below 2%.  

Eco-Certifications and Sustainability  

1100 aluminum foil aligns with global green building standards, boasting a 98% recyclability rate and 70% lower production energy consumption than copper, meeting LEED certification requirements. A Beijing CBD skyscraper earned an additional 8 points in green building ratings by adopting aluminum foil systems. In medical purification, antibacterial 1100 foil combined with HEPA filters reduces bacterial counts in operating rooms to below 5 CFU/m³—three orders of magnitude better than traditional materials. Moreover, the foil's inner surface smoothness (Ra ≤ 0.8μm) lowers airflow resistance to 0.018, reducing fan power by 15–20% at equivalent air volumes.
