Anyone tried this stuff? Looks good in the infomercial. I have an aluminum Surco roof rack that I was thinking of using this stuff on. Its riveted/bolted together and rattles like mad. I want to make it one solid piece by soldering the joints. I think this would be good to carry on the trail as well for emergency repairs to aluminum housings ( ie Trannys, alt brackets and the like) It only requires heat from a propane torch whick I usually carry on the trail. Thoughts on this stuff??

Aluminum Soldering Rod

I have not tried that stuff. it looks like it can do amazing repairs. Here is the website-


Durafix

Wow! Looks amazing. Would be useful to have some. <img src="/forums/images/graemlins/kewl.gif" alt="" />

Thanks for posting that. It's definitely interesting. I'm surprised at the tensile strength rating, which is better than 6061-T6 aluminum (medium strength/fairly common aluminum).

Still might have a problem about thermal expansion/contraction, just as with welding aluminum, but not sure how big a difference it would be. When welding aluminum the weld is weaker than the rest of the material being joined. So this could be an interesting alternative.

Well, A few years back I was TAD to the east coast and saw an informercial on the stuff. Its amazing that you can use it with a propane torch making what would seem to be great emergency field repairs to aluminum. I guess I'll have to order some and give it a try.

Man I hate when people mystify their holy grail product. Aluminum Soldering using zinc been around for long time. Making flux core soldering/brazing/welding wire just as well.
Oh the magic trade secret alloy is probably some variety of AL802 soldering alloy (high temp soldering or low temp brazing if you will) which is 98% pure zinc. Which explains tensile strength also.
For better details look up here http://www.handy-one.com/htmdocs/products/aluminum_filler_alloy_metals/al802.html

For field repairs you need darn good torch. Aluminum conducts heat very well so it tends to escape welding/soldering area.
For brazing/soldering to work you got to heat up base metal to solder melting temperature and keep it there. Aluminum is particularly nasty for this since it conducts heat so well. It's no coincidence they keep those aluminum peaces in a heavy metal wise. I bet if they pointed thermometer at those they would be conveniently pretty hot (preheated). I mean it's no gimmick or magic, that definitely stuff works but you need to use right technique in right conditions. Soldering Monty's cracked t-case in field, forget it. In the shop, with practice definitely possible.

Thanks for the input. Anything can be made to look great on TV. If it looks too good to be true it most likely is I guess.
