Blue Fin Hydrophilic Coated 3104 H14/H16/H18 Aluminum Foil for HVAC Fins
In modern HVAC (Heating, Ventilation, and Air Conditioning) manufacturing, the material used for aluminum fins plays a critical role in heat exchange efficiency, durability, and long-term reliability. Among various fin materials, 3104 hydrophilic aluminum foil has become one of the most widely used solutions due to its excellent corrosion resistance, outstanding thermal conductivity, and stable forming characteristics.
What is 3104 Aluminum Alloy?
3104 aluminum alloy belongs to the 3000 series Al-Mn alloy, known for its high strength, excellent formability, and corrosion resistance. Compared with pure aluminum foil, 3104 alloy maintains superior workability while offering higher mechanical strength, making it ideal for fin forming processes.
Blue fin hydrophilic aluminum foil applies a special surface coating that allows condensate water to spread evenly across the fin surface (contact angle can be reduced below 10°) and flow quickly along the fin. This effectively eliminates “water bridge” blockages in air passages, improving heat exchange efficiency by approximately 5%, contributing to energy savings.
3104 hydrophilic aluminum foil is available in multiple temper grades: H14, H16, and H18, providing flexibility for manufacturers to use it in residential, commercial, and industrial HVAC systems across various condenser and evaporator applications.
Key Advantages of 3104 Hydrophilic Aluminum Foil
3104 aluminum foil has outstanding elongation and forming performance, allowing manufacturers to produce complex fin structures through high-speed stamping without cracking.
Compared to alloys such as 8011, 3104 offers higher tensile strength, improving the mechanical stability of heat exchanger fins.
The manganese content enhances resistance to atmospheric and moisture corrosion, making it suitable for humid environments.
The foil has a smooth, clean surface that ensures strong adhesion between the aluminum substrate and the hydrophilic coating.
