Bonding AL to AL

onefastmustang · #1 (**permalink**) 05-28-2009, 09:12 AM

I have two pieces of aluminum I need to bond together. There will be no stress between them once fully assembled but they do need to be secure and fluid leak free. Any suggestions on an epoxy?

Pop rivets and Sumo glue should do it. That is as long as the fluid does not desolve the glue/sealant.

Just a suggestion.

JB Weld works miracles.

You can't weld it?

It's a very small part. I would be concerned with warpage from heat. I have gotten a few good ideas now though. thanks guys.

3M makes a wonderful two part epoxy for this called "Automix" part number 8115. Used mostly for bonding quarter panels and door skins, should work well with what you need it for.
