Not to say whether or not it is appropriate for what you suggest, I do have some of the rod you mentioned. It is called M-F rod fluxless brazing rod. Sold by Gene Wagner R.R. 1 Box 456 Farmland, In. 47340 Ph. 765-4686931. I have had it a long time, so I don't know if the contact info is still good. Says on the label that it is for Zinc and Aluminum alloys.
