Fins are made of a variety of materials, and the heat transfer performance of fins varies depending on the material used. Commonly used fin materials include copper and aluminum.

Aluminum fins have better heat dissipation capabilities and lower cost. Therefore, aluminum is commonly chosen as the raw material for fins.

Aluminum foil for Fin

Aluminum fins are a lightweight, formable and corrosion-resistant material used in everything from car radiators to heat shields. It can also be used in a variety of heating, ventilation and air conditioning (HVAC) equipment such as aluminum radiators, aluminum evaporators and aluminum condensers.

Aluminum Fin Stock Material Properties

1. Thermal Conductivity: Aluminum is chosen for fin construction due to its excellent thermal conductivity. The ability to efficiently transfer heat from the source to the fins is crucial for the overall effectiveness of the heat dissipation process.

2. Lightweight Nature: Aluminum's lightweight nature makes it a practical choice for applications where weight is a consideration, such as in the aerospace and automotive industries.

Aluminum Fin Stock Specifications

Aluminum fin is a lightweight, formable and corrosion-resistant aluminum alloy material. It is usually made by rolling aluminum foil using 1000, 3000 and 8000 series aluminum alloy metal multiple times through an aluminum foil rolling mill to form a thin and flat Metal plate. These sheets usually come in the form of aluminum coils, but can also be cut into aluminum strips.

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.

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.

Coated aluminum foil/fin blanks are mainly used in the production of heat exchanger fins such as air-conditioning condensing evaporators, refrigerator frost-free evaporators/finned evaporators, commercial refrigerator condensing evaporators, automobile air-conditioning condensers and evaporators, etc.

Aluminum foil for air conditioning heat exchanger fins

We can supply 1000 series, 8000 series aluminum foil, etc., or according to customer requirements.

Refrigerator fins anti-frost coated aluminum foil

New functional hydrophobic coating is applied to refrigerator heat exchangers to improve frost formation and improve the energy efficiency level of refrigerator products.
