thread338-355431: Methanol/Ethanol corroding metals

Hi there,

I bring back a topic I started some time ago (thread338-355431: Methanol/Ethanol corroding metals).

We are building a prototype of a cooling shell, the final material selected was aluminum alloy Alu 3.3206 - AlMgSi0,5 - EN-AW 6060

It has a good thermal conductivity, it is easy to machine and it has good corrosion resistance.

Apparently, it is not easy to get in thick plates (blocks). We need 60mm (~2.4 inches)

The supplier company has proposed 3.2315 - AlMgSi1- EN AW-6082

Does anybody have experience with this?
Our first choice has ~25% better thermal conductivity, but I worry more about the corrosion

In the previous post we didn't talk about aluminum types; in the "NACE International, The Corrosion Society (2002). Corrosion Survey Database (COR·SUR). NACE International" these grades are not mentioned
