So it's good for brazing very thin sheet metal. And it's reccomended on some of the newer cars, because of the alloy they're using.

I've been tig-brazing the bracketry on my stainless tanks. Melts faster, less warpage. And the silcon-bronze is a good color match to SS that has been tig welded.

There is a problem with electric brazing cast though. You still need to pre-heat so much with an acetylene torch that you might as well just gas-braze to begin with.

Tig-braze needs a special no-zinc rod. Any zinc will boil off at electric arc temps, making gas clouds, leaving zinc oxide all over.

But what was the alloy? Monel? Phosphor-bronze?
