do any of you have any experience with these alum brazing products like durafix? does it work? strong enough to hold alum ic pipes together?

 

I've used it....I would say yes definitely it would hold intercooler pipes together.

I used it to fill a section of a B18 block that had the timing belt side motor mount broken off in an accident. I filled it with "alumilloy", tapped it, and it has held perfectly for over a year.

It claims a tensile strength of over 30,000 psi which is fairly strong. It would certainly work as long as you flow the stuff well...it's hard to get it to flow nice at first. Practice a bit with it so that it flows very cleanly and evenly, and it'll definitely work.

 

are there any rods that are better than others?

 

I decided to get a starter set of the Super Alloy 5 from Muggyweld.com. Watching the videos on that site were really the deciding factor for me against the durafix stuff.

I do think that both would work well, very well, for joining two non-ferrous metals, the super alloy 5 is able to be anodized, while durafix isnt, and I need that ability for my project.
