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
1. Excellent Formability

3104 aluminum foil has outstanding elongation and forming performance, allowing
manufacturers to produce complex fin structures through high-speed stamping
without cracking.

2. High Strength

Compared to alloys such as 8011, 3104 offers higher tensile strength, improving the
mechanical stability of heat exchanger fins.

3. Superior Corrosion Resistance

The manganese content enhances resistance to atmospheric and moisture corrosion,
making it suitable for humid environments.

4. Good Surface Quality

The foil has a smooth, clean surface that ensures strong adhesion between the
aluminum substrate and the hydrophilic coating.
