none in particular.. Most good 2 part epoxies would work. I don't know
that I'd use 5 minute epoxy, but one of the slower cure ones should
work. For "around the shop" non-critical stuff,I've used a 1 hour cure
type that I got at the hobby shop.
For most epoxies, surface prep is the key. For aluminum it probably
makes a difference if it's bare aluminum, or it's had some sort of
chemical conversion coating (like anodizing). Solvent, then physical
abrasion, then cleaning. Sometimes you need some sort of acid treatment.
If you want ultimate performance, google for "epoxy for aluminum" and
you'll probably turn up something specialized for your application
Where I used to work, we had a variety of 2 part epoxies for various
materials: some optimized for fiberglass composites, others for metals.
And, in various viscosities.
