Fin material


As heat exchangers are used in a wide variety of environments, they require a range of construction materials. Several different fin material options exist, allowing the heat exchanger to operate in environments ranging from mild office applications through to more aggressive coastal and manufacturing environments. Three key fin materials are offered: the standard being natural aluminium, a pre-coated aluminium called “Blue Fin”, and copper. “Blue fin” offers a further level of resistance to environmental conditions, with copper offering the best possible protection.

Natural Aluminium

Natural Aluminium is the standard fin material used in all Coils Australia heat exchangers due to the excellent cost/performance combination it provides. When coated with Standard Finish corrosion protection this provides a highly cost effective solution for general operating conditions.

Blue Fin

Blue Fin is a high performance pre-coated aluminium fin material. Blue Fin appears as an anodised finish with a gloss blue tone that remains flexible. The Blue Fin coating is applied to the raw aluminium fin stock. For harsh environments that are particularly corrosive to aluminium, Blue Fin is the solution.


In applications where the heat exchanger can’t be easily replaced, it demands that the materials used in the coil provide the best possible corrosion resistance to maximise service life.

With it’s superior thermal conductivity, corrosion resistance and strength compared with aluminium, copper is the ideal choice for demanding environments.

Copper finned heat exchangers are more suited to environments where improved thermal performance is required. They are also suited to more abrasive environments because unlike a pre-coated fin, a copper finned coil will not wear out and fail.
