What Are Aluminum Extruded Fin Tubes?
Aluminum Extruded Fin Tubes are manufactured by inserting a base tube (fluid handling tube) into a thick aluminum sleeve. Through a cold extrusion process, fins are formed directly from the aluminum sleeve material, creating a seamless, high-performance heat transfer surface.
These specialized tubes eliminate the risk of galvanic corrosion at the fin root while providing exceptional mechanical resistance and long-term performance consistency.
Aluminum Extruded Fin Tubes Advantages
Material Flexibility
Compatible with any base tube material including copper, stainless steel, titanium, duplex, and more.
Exceptional Bond Strength
Extrusion process creates a permanent mechanical bond between fin and tube.
Corrosion Resistance
Aluminum fins provide excellent atmospheric corrosion protection in harsh environments.
Thermal Efficiency
Maintains consistent performance over time with minimal degradation.
Galvanic Corrosion Prevention
Complete enclosure of tube eliminates corrosion at fin root.
Long-term Performance
Resists performance degradation from fouling and thermal cycling.
Performance Advantages
Heat exchanger performance degradation primarily occurs through two mechanisms:
- Fouling Accumulation: Impurity buildup in fluids increases thermal resistance.
- Thermal Cycling Damage: Repeated expansion/contraction weakens fin-to-tube bonds.
Aluminum extruded fin tubes resist both degradation mechanisms through their monolithic fin structure and cold-formed bond, ensuring consistent long-term performance in demanding applications.
