JB Weld is probably the highest temperature epoxy resin glue - certainly was when I looked into the issue. Good enough for a non-combustion chamber repair to an engine block.
There are two grades of Araldite, the stuff that sets in few minutes, and the traditional wait 24 hours one. The latter is of course stronger, but the quick one has its uses for things one might want to take apart again as if you can boil the object in detergenty water, the epoxy becomes like cheese.
But you'll never have any success with any kind of glue if you don't thoroughly degrease the surfaces first. I generally tell folk, 'do it properly, and then do it again'. Epoxy should stick aluminium no problem, and without trying for myself, I would suspect a surface that was still slightly greasy in the event of failure.
