Aluminum solder source?

Northern Tools (formerly known as Northern Hydraulics) has a version. I've used it successfully on storm window frames, etc. I would not trust it for anything critical, but I have been able to reproduce the can trick, and I tore the bottom out of the Pepsi can before I could get the solder to let go.

IIRC, the original was Aluma Weld in Deland, FL.

When I went to the State finals in Radio aircraft flying in Ca. - There was a guy / gal that was filling a bottom of a can with 'al solder' - I think it was a zinc based solder. I bought some zinc based at a hardware - in long sticks.

Real Al solder - is tin. Tin solders to Al with a good flux. Kester sells a silver box of Al solder in hardware stores.

Any welding supplier can order it. UTP sells a version that I have been demoing to my students for years. Useful stuff if you just need to plug a hole in an aluminum boat or gas tank.

It has too much zinc in it to have any kind of ductility, so you want to make sure your joint design doesn't allow the part to flex.

Hmm, a few posts say this solder is high tin content. The data I have seen for Alu solder says high lead (80.1% lead, 18% tin, 1.8% silver). Take a look at

The cheap "miracle rod" fluxless aluminum solders sold at flea-markets are an aluminum/zinc alloy.

You also have silver. I don't see any info on the pure tin any more. So much has happened in the solder world with this NO LEAD rules running the world of electronics crazy not.

It isn't just on the pcb - but none inside the IC or parts. That is a big step that is harder than some thought. Likely improved versions have been developed for Al.
