The threads in the body are uncoated steel so that'll really stick. The bolt flange may or may not stick to the aluminum if it scratched through the alodine (probably OK on the aluminum).

Also FWIW, 7075 aluminum is almost as stiff as 2024 (72 GPa vs 73 GPa) and probably much more readily available. It'll also act more like 6061 for various processes.
Thanks!

I'm not too worried about galvanic corrosion in this environment. Maybe if it was Wet Nellie.
Al was sourced from McMaster-Carr. Doesn't get much easier than that.
