As a core component of HVAC heat exchangers, the performance of aluminum fin stock directly determines the energy efficiency and lifespan of the air conditioning system. Haomei Aluminum’s specifically developed gold hydrophilic pre coated aluminum foil stock precisely matches global market demands, integrating advanced material technology and precision coating processes, making it a preferred material for leading global HVAC manufacturers.
Our gold color hydrophilic coated aluminum fin stock uses 8011/3102 series aluminum alloy as the base material, with a thickness ranging from 0.08mm to 0.5mm, and a width that can be customized from 15mm to 1000mm according to requirements. Our independently developed water-based acrylic gold coating boasts superior performance: a contact angle ≤15°, enabling rapid condensate spreading without bridging, improving heat exchange efficiency by 10-15% compared to ordinary aluminum foil; in a 5% NaCl neutral salt spray test, it achieves a corrosion resistance rating of R.NO≥9.8 after 500 hours, and the corrosion area after 72 hours of salt spray exposure is less than 0.02%, making it suitable for harsh environments such as high-salt coastal areas and highly polluted industrial environments; the coating also possesses antibacterial and anti-mildew properties, effectively solving the odor problem in air conditioning systems.
In a Middle East HVAC project undertaken in 2025, our gold color hydrophilic aluminium fin stock successfully addressed the core pain point of traditional aluminum foil’s rapid corrosion in high-salt and high-humidity environments. This product was applied to 50,000 commercial air conditioners, and after 12 months of continuous operation, the heat exchange efficiency remained stable, and system energy consumption was reduced by 8% compared to the original solution, gaining high recognition from local partners. In another Southeast Asian data center cooling system project, the product’s superior thermal conductivity (31% higher thermal diffusivity than traditional aluminum foil) ensures efficient heat dissipation for precision equipment. Simultaneously, its low air resistance reduces system noise by 15dB, precisely meeting the stringent requirements of the data center operating environment.
Targeting a diverse global market, the product strictly complies with YS/T95.2-2009 and international HVAC material standards. Alloy grades, thicknesses, and coating formulations can be customized according to different regional climate characteristics and customer process requirements. The gold coating not only enhances corrosion resistance but also possesses excellent formability, adapting to high-speed stamping of various heat exchanger fins without coating peeling.
