Pre-Coated Aluminum Fin Stock for Heat Exchangers
Aluminum fin stock, with its excellent thermal conductivity, is utilized in heat exchangers for room/ package air conditioners and large refrigerators.
Kobe Steel meets customers' needs for multifunctional fin stock with our superior coating technologies.
Features
Our product lineup offers varieties of properties that are essential for heat excahngers.
(1) Hydrophilicity
Moisture adheres to the fin surface as a result of condensation during cooling. Our highly hydrophilic aluminum fin stock improves the heat exchange rate of air conditioners and prevents water splashing.
Condensation on the heat exhanger
(2) Corrosion Resistance
When heat exchangers are used outdoors for long periods of time, its aluminum base corrodes with moisture and suspended solids. Corrosion-damaged aluminum severely lowers heat exchange performance. Our corrosion-resistant coating prevents corrosion of the aluminum base. We also provide products for harsher environments, such as places susceptible to salt damage.
(3) Press Formability
Forming a lubricant layer improves press formability and lowers wear on the press die.
(4) Framework for Development
We are promoting Groupwide R&D efforts with the aim of developing products with high added value.

Pre-Coating Technology
We have chemical conversion coating and multiple layer coating technologies, allowing us to meet our customers' multifunctional fin stock needs.
Technology to Enhance Functionality through Mutiple Layer Coating
Coatings as thin as a few microns are layered together to create materials with a wide range of performance properties, including hydrophilicity and corrosion resistance.
Application Example 1: Self-Cleaning Fin
The special coating washes away any dirt that adheres to it with condensed water, maintaining a clean coated surface.
Application Example 2: Dust-Resistant Fin
The special coating prevents dust from adhering and maintains a clean coated surface.
- *Kanto loam (JIS test powder 1, 11 types) is used for dust components.
Aluminum Alloy
We offer a wide range of materials, including our unique highly formable materials with good press formability, allowing us to propose aluminum materials suited for a variety of fin material forming processes while meeting quality and tempering specifications.
- (1) 1J70
With high press formability, 1J70 can lower the costs by making the material thinner, while improving heat exchange performance and workability.
- (2) 1200
Ordinary aluminum with a purity of over 99.0%
Manufacturing dimensions (mm)
Thickness: 0.08-0.2
Width: up to 1600
