I was just wondering if other trades share our concerns here
After all, there are aluminum heads for cars.
Myself, i spent a decade putting together 6061 AL parts to specs of 1/10,000. The variables included all enviromental, as well as those introduced . The engineering aspects did not include any one-liner fits all explanations.
One item i do use is scotchcoat, which seems to isolate a termination well.
