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.
