Chemistry question on aluminum

Hi,
I am not sure if I am getting paranoia about this...

Nowadays, there are many equipment (amps, speakers, etc) that are made from aluminum; from a slab, ingot, extruded and other processes. And I am a sucker for the raw industrial silvery color Aluminum looks. I just dig them. (Think YG acoustics, Audiomachina, Modwright, Jeff Rowland, Acoustic Signature TT, et al)

But I live in the hot and humid tropics. A friend, knowing that I failed Chemistry in school, put a scary thought in me that white powdery substance will form and corrode them in the long run.

Anyone care to give me a Chemistry 101 lesson on this with respect to Audio equipment?

Thanks.

Salt water air will penatrate treated and untreated aluminium almost as quick and turn it to dust quick.

For homes next to the beach I'd recommend keeping AC on all the time to keep the moisture at its minimum.

Far more manufacturers using aluminium chasis. Most of heatsinks are aluminium. The lifespan of aluminium chassis is far larger than human lifespan so nothing and nothing to scratch your head about in any case. Raw aluminium can be toxic if digested so it's not recommended to cook a food on untreated aluminium. Other than that there's no toxines getting airborn off the aluminiumn surface.
