Default Is there an epoxy stronger than JB Weld?

I need to fill a small hole in an aluminum part. JB Weld can crumble. There must be a product that is stronger then JB Weld.

Try a epoxy called Super Mend it works very well and is a lot stronger. It comes in a yellow and white box w/red writing. I have gotten it at Ace hardware.

What is this for?

Depending on what the part is and how large the hole is, patching or puddle-filling the hole with a TIG could be much better ideas than an epoxy.

As far as epoxies go, I'd recommend Master Bond's EP22. SuperMEND is only good for intermittent exposure to 150 F, and it's not terribly strong. If you're a fan of SuperMEND, the same company (GOOP), makes an epoxy called "SuperWELD" that is much more durable and probably wouldn't be a bad choice, either.

Every type of epoxy has different properties. It's kinda hard to recommend something without knowing what the part is and what sort of environment it's gonna see...

Belzona is the strongest 2 part epoxy style product made and is used to patch holes in blocks and other similiar things and is drillable and tappable. It's regularly used in the trucking industry. It makes JB weld looks like a childs product.

+1 for belzona its an industrial product that is outstanding. You will want to use the R-METAL style. hang on to your check book when you see the price

I think it depends more on the hole's particulars
than the epoxy. Like, forget having anything
plug a hole in sheet metal or thin-wall casting
permanently, thermal expansion cycles will bust
it free eventually.

Never seen JB fail myself; under what use has
it "crumbled"?

If you're looking to (say) plug a TB blade hole,
then peening in a soft aluminum plug or doing
a quick weld-blob would be more likely to last.
On thicker stock, tapping the hole and putting
an epoxy-set pipe plug (or Allen screw for small
jobs) might be better than epoxy alone - at
least you have some mechanical "keep".
