    I have two pieces of aluminum metal. how do i bond them?

    so uh, i'm making this metal bracket, see? and i need to know how to make these two pieces that i have stick together permanent-like, see? and i need one of you geniuses to advise me on which type of solder i need, see? and what kind of iron i need...see?

    ok, enough of that. i just need to know if i actually need a soldering iron to do this, and if i do, what kind of iron and what kind of solder? or is there some sort of bonding magical stuff that will suffice?

    i am creating a bracket for my motherboard [and components] that will sit inside the dash, where my HU used to be.

    The only thing that I would know to use would be rivets. I don't think you can solder aluminum, only weld.

    Ya rivets sounds good, I hear welding aluminum is tricky. At least more tricky than steel.

    Solder is definitely not the best choice for structural useage (holding together two pieces of metal) its really only use is electrically (holding two spliced wires together, a wire to a PCB...).

    I think what Ill1 and Pudge said with the rivets is your best choice. Although you could spot weld them to kind of 'tack' them together depending on the strength of support you will need. Not easy but not as hard as welding two pieces of aluminum together with a nice looking seam.

    To my knowledge, an aluminum welder is $$$ and probably isn't the way to go. You can cut and bend a piece of sheet metal into the bracket shape that you want. That would be the way I would take care of it now that I think about it. You just might have to sit down and figure out where to cut and fold a 2D sheet into a 3D bracket.

    Use stuff like hot glue or eproxy, wrapped in tape.

    well see - this is what i do have - 1 aluminum sheet [12*36 in] a pre-made bracket [composition unknown] and an already bent-to-my-liking piece of metal [composition unkown]. What's cool is that i found these pieces and i have fashioned an enclosure for my mobo. the pieces fit together like a dream...it's just a matter of fastening them securely.
