Hydrophilic Aluminum Foil Roll H22 H24 (0.095-0.13mm x 200-1300mm) for HVAC Heat Exchanger Fin Stock

In modern heating, ventilation, and air conditioning (HVAC) manufacturing, heat exchanger efficiency relies heavily on fin stock performance. Hydrophilic coated aluminum foil rolls in H22 and H24 tempers offer the ideal combination of deep-drawing formability, rapid condensation drainage, and long-term corrosion resistance for high-speed fin production.

Engineered for High-Efficiency Heat Exchangers

Condensation buildup on evaporator fins often creates "water bridges" that block airflow, increase fan power consumption, and elevate system noise. Our hydrophilic aluminum foil solves this through an advanced surface coating technology:

Low Water Contact Angle: The specialized surface treatment reduces the water contact angle to below 10°, allowing condensation to form a thin water film and drain smoothly.

Enhanced Thermal Performance: Continuous water drainage prevents air duct obstruction, maximizing heat exchange efficiency and delaying frost formation in heat pumps.

Superior Salt Spray Resistance: Epoxide/organic-inorganic hybrid coatings protect the aluminum matrix against humid climates and coastal salt spray (NSS ≥ 500h).

Key Stamping & Processing Advantages

Designed for automated, high-speed stamping presses running up to 200–300 strokes per minute, our foil guarantees minimal downtime and maximum die life:

1. Consistent Mechanical Properties: Strict tensile strength and elongation control (H22/H24) prevent pinholes, tears, or collar cracking during collar stretching and flanging.

2. High Coating Adhesion: The hydrophilic film resists micro-peeling and powdering during intense mechanical deformation.

3. Tight Gauge & Camber Tolerance: Uniform thickness across 0.095 mm to 0.13 mm prevents die jamming and ensures consistent fin density.
