Types of Aluminum fin stock

Coated Aluminum Fin Stock

Coated aluminum fins have excellent brazeability, resistance to core dissolution and high temperature collapse, making the heat exchanger lighter.

Uncoated Aluminum Fin Stock

Uncoated Aluminum Fin Stock is the most basic heat exchanger material. It consists only of the core layer without any coating. It can be used in a variety of applications including automotive radiators, intercoolers, oil coolers, evaporators, water tanks, heaters, and various air conditioning radiators.

Bare (Uncoated) Aluminum Fin Stock
Pre-coated Aluminum Fin Stock
Hydrophilic Aluminum Fin Stock
Corrosion-Resistant Aluminum Fin Stock
Superhydrophobic Aluminum Fin Stock
Self-Lubricating Aluminum Fin Stock
Anti-Mildew Aluminum Fin Stock

Bare Aluminum Fin Stock

Bare Aluminum Fin Stock is used in a variety of automotive radiators, heat shields, and heating, ventilation and air conditioning applications. Fin blanks are mainly made of 1000, 3000 and 8000 series aluminum alloys.
Pre-coated Aluminum Fin Stock

The surface of pre-coated foils has been treated to provide more functionality than uncoated foils. Many of the corrosion-resistant aluminum foils and hydrophilic aluminum foils mentioned below can be classified as pre-coated aluminum foils.
Hydrophilic Aluminum Fin Stock

Hydrophilic Aluminum Fin Stock is a hydrophilic treatment of aluminum foil. It is coated with a hydrophilic layer on its surface through a special process. The condensed water in the hydrophilic aluminum foil will spread quickly without condensing into water droplets. This not only increases the heat exchange area and speeds up the cooling and heating speed, but also effectively avoids water condensation caused by air flow noise.
Corrosion-Resistant Aluminum Fin Stock

This type of fin material is designed to resist corrosion, which is critical in applications where the fin surface is exposed to harsh environmental conditions or corrosive substances.
Superhydrophobic Aluminum Fin Stock

Superhydrophobic materials are extremely waterproof. Superhydrophobic aluminum fins are designed to repel water, potentially preventing problems such as freezing or the accumulation of water droplets in some applications. Superhydrophobic Aluminum Fin Stock has the opposite surface properties of hydrophilic aluminum foil. Its purpose is to prevent condensation water from remaining between the heat exchange fins.
Self-Lubricating Aluminum Fin Stock

This type of fin can have a coating or treatment that imparts self-lubricating properties, which can be useful in applications where friction reduction is important.
Anti-Mildew Aluminum Fin Stock

Aluminum fins with mildew-resistant properties may be treated or coated to prevent the growth of mold or mildew. Mildew-proof aluminum fins are mainly used in the air conditioning dehumidification part of indoor units. Its main function is to prevent the surface of the heat exchange fins from becoming moldy due to long-term use or storage, thereby improving the ventilation quality of the air conditioner.

Applications of Aluminum Fins

Aluminum fin stock is widely used in the HVAC industry for the production of heat exchanger fins. In addition, it is widely used in the automotive industry for the manufacture of radiators and condensers. Its excellent heat transfer properties, lightweight properties and corrosion resistance make it ideal for these applications.
