Aluminium fins are formed from a bimetallic tube consisting of a base tube and an aluminium muff tube. The fins are formed on a cold rolling process from the wall thickness of the aluminium muff tube. Extruded fin gives very good corrosion protection to the base tube, as the base tube is not visible to the atmosphere inbetween the fins.
Fin Material - Aluminium (or) Copper
Tube Material - No theoretical limit
Maximum operating temperature: 325 deg C.
