Hi Joe,
I purchased directly from the vendor using their $65
special for 1 lb of the stuff. I doubt that they would sell lesser amounts
- but I have not asked.
In any case, that is the stuff and I have found it great
to use. I tried at least 3 other aluminum brazing rods and got little more
than puddles of the stuff sizzling around on the metal I was trying to braze but
no joining. No-doubt my lack of technique - but this stuff is much less
critical. I have brazed .048 thick wall 6061T6 to a heavy aluminum
manifold casting with no problem. They tell you to brush with a stainless
steel brush while brazing but I just brush it clean of scale with the brush
initially and braze away(set too many wooden handle stainless steel brushes
on fire while trying to brush while brazing - must be like chewing bubble gum
and walking at the same time {:>))
I initially started out using the MAP gas because of hits
higher heat content, but then found that regular (cheaper) propane would
do just fine provided you had a high BTU torch (for heavy stuff like
castings). You do have to set it for a high BTU flow if you are brazing
anything heavy, but smaller torches work well for lighter stuff.
Here's a photo showing the bottom tubes brazed to the
aluminum manifold casting and the upper tubes brazed to the 3/8" thick 6061
plate. Not too messy.

Ed Anderson,
When we spoke a couple of weeks ago at KLKR, you
mentioned a great brazing rod for aluminum. Was it New Technology's
HTS-2000. If so may I ask where you bought, direct from the vendor or
were you able to find a smaller quantity than 1 lb.. If this is not the
vendor or product may I ask again what it was.
Thanks,
Joe
