Hey guys,

I took a frame building course a few years back where we used GF-72 Nickel Silver for tacking tubes and an initial joint which was then covered with brass filler.

I really enjoyed working with nickel silver, but whenever I go to do an order from BFS or other places it is sold out, being in Canada I would rather not do an entire order just for some filler.

So my question to you guys, is what exactly it is? It is impossible to find anything with a similar make up from any of my usual brazing suppliers up here. I have recently read about Aufhauser A-56T, which doesnt look to be the same but the properties description sounds very much like it.

Hoping to get some more generic terms to search for, the welding suppliers don't seem to be too much help in finding out an alternative.

Thankyou for any help!

JB
