Choosing between PE, HDP and PVDF coated aluminum is not simply a question of choosing “good, better or best.” The correct coating depends on where the aluminum will be used, how long its appearance needs to remain stable, how severe the UV, moisture, salt and pollution exposure will be, how the material will be formed, […]

Choosing aluminum fin stock by alloy number alone can be misleading. 1100, 3003, 3102 and 8011 are all used in heat exchanger fin production, but they do not provide exactly the same balance of strength, formability, foil-gauge capability and processing behavior.   For HVAC and refrigeration manufacturers, the better question is not simply “Which aluminum […]

Hydrophilic and bare aluminum fin stock can both be formed into thin heat-exchanger fins, but their surfaces behave differently once condensation appears. Bare fin stock relies mainly on the characteristics of the aluminum surface, while hydrophilic fin stock uses a functional coating designed to improve surface wettability so condensed water spreads more readily instead of […]

When a buyer asks for color coated aluminum coil with protective film, the aluminum coil is still the main product being purchased. The protective film is a temporary surface-protection option intended to help preserve the coated face during downstream processing, handling and transport. Whether it is necessary depends on the appearance requirement, coating finish, fabrication […]
