Thermal conductivity of alluminum, anodized/oxodized.
Thermal conductivity of alluminum, anodized/oxodized.
(OP)
I found this forum searching for info on open headers causing burnt exhaust valves and found some very good information and what appear to be intelligent people. So I thought I would pose a question that I have wondered for sometime.
Which has higher thermal conductivity, anodized aluminum or lightly oxidized aluminum? Any solid information would be appreciated.
I ask for intercooling purposes and the choice to anodize intercoolers or not.
Thanks a lot.

One thing is that as the surface gets smoother the transfer between the aluminium and the air goes down.
One benefit of the Anodizing process is that the coating thickness and surface finish are more controlled than the oxided surface film on a raw aluminium piece. However the Anodized coating is going to be thicker.
