View Full Version : Aluminum solder

09-25-2002, 10:58 PM
I have seen demos at car/bike shows where a guy solders with an aluminum alloy and just uses low heat. Benzomatic or cigarette lighter flame.
I was not interested in it at the time so I did not pay much attention to it.
Has anyone ever came across this and does anyone have any info on it ?

There are at least half a dozen vendors selling this magical rod which will solder aluminum at low temperature. I've used ones from two different suppliers and besides being relatively expensive (about $2-3 per 12" rod), it's prone to producing cold solder joints. It may be good for filling in cracks and holes, but for anything even remotely structural I would not recommend it.

If it wasn't so expensive, it may actually make a good low temperature casting material.

I split a package with a friend, years ago. Very seldom use it. It does work, sorta. I don't have a lot of experience using it, but I think if you follow the directions closely re: cleaning and scratching through the surface oxide to get a good bond, you can get decent joints. Like Rotate though, I'm not sure how much I'd trust it for serious structural work.

I was going to use it for structural work. But, not now.
Guess I'll go back to Heliarc.

Any Lead free solder will work - or is it Antimony free? It is one of the two. If you life depends on it it may come in handy, other wise - forget it, it still does a poor job.
