This fin type is formed from a bi-metallic tube consisting of an aluminium outer tube and an inner tube of almost any material. The fin is formed by rolling material from the outside of the exterior tube to give an integral fin with excellent heat transfer properties and longevity. Extruded fin offers excellent corrosion protection of the base tube. Maximum operating temperature for this fin type is 280 C.Fin material: AluminiumTube materials: steel, copper, stainless steelBase tube O.D.: From 5/8" (15.88mm) to 1 1/2" (38.1mm)Fin height : From 1/4" (6.35mm) to 5/8" (15.88mm)Fin Thickness: From 0.012" (0.30mm) to 0.020" (0.51mm)
