...okay,first off-i feel retarded even asking this,but i am having a hard time figuring this out.
i have a customer with an Ebay all aluminum radiator.the neck looks to be pressed into the upper tank.it's leaking around this connection.i'd like to weld the two pieces together to fix it,but i'm not 100% sure the neck is aluminum.
how can i find out for sure?obviously i don't want to start trying to weld on it without knowing for sure.
if it was aluminum,i can't see why they wouldn't weld it also.every other piece of the rad is welded,so that makes me think it may be a different material.the other thing that makes me think it may be another material is i think aluminum would be too soft for that part,since you've got the cap twisting on and off it.it seems to me you'd want a less malleable material for that.i've never paid that much attention to other aluminum rads,so i don't have much to compare it to.
if it is another material,what would ya'll recommend to bond these two?could plumber's solder work?what about simple JB Weld?
Thanks for any input.

tap it with a sharp punch or hammer. Stainless will ring, aluminum will thud. In such a small part you'll need to use a sharp tool to get it to ring, but you'll be able to tell the difference. Also if you tap it with a sharp object aluminum will leave a major mark. Stainless will only leave a small dimple.

 

magnet?

 

Most stainless steels aren't magnetic.

 

I've never seen a stainless radiator radiator

 

no one makes a stainless radiator. its a very poor conductor of heat compared to copper or aluminum.

thats what was gonna say. i'd think a flat head screwdriver would problably be able to leave a good scratch if its aluminum.

 

Try looking at the lip where the cap screws on.

If it's aluminum, it would be quite a bit thicker in order to stand up to removing and installing the cap.

I'd bet it's steel, but would question if it's stainless.

A magnet would verify if it's standard mild steel. (it's the lack of iron in stainless that makes it stainless. It's the iron that's magnetic. Different grades of stainless do have a certain amount of iron)

Get a dremel or a die grinder or something and hit it with that. Aluminum will not spark, stainless will

 

Just scratch it. Something stainless and something AL. Then go scratch any part of the radiator in question. You'll be able to tell the difference very easily.
