i just saw the infomercial on tv.. has anyone ever used this? i was thinking of using it to bond DIY intercooler piping.. will it hold?

 

hell no. unless this is some kind of miracle, you cannot acheive strong welds unless the filler is joined completely with the material to be welded. this means that they both need to be liquids before they are cooled. they say you can acheive the weld without high temperatures which is bs unless they found some kind of way to melt the metal without high temperatures...

 

dont use it!

 

It works great on intercooler pipes and patching old intercoolers that leak. I would not use it for heavy stuff(1/4" or thicker) but most of the aluminum we use on our cars is thin stuff.

 

it's just a common zinc brazing stick - think soldering, but with higher temps. I have used different brands of pretty much the same thing and have gotten it to bond pretty well with aluminum, but more often than not, the stuff just sticks to the surface, cools off then falls off. If you're looking into doing some brazing, look for a good fluxing system and a filler rod designed for the flux, etc.

 

I think this particular product is a zinc/aluminum eutectic.

I bought some, to construct a custom intercooler. We'll see how it turns out. I can't afford a TIG welder nor do I have a 220VAC outlet.

 

seen the commercials too.. it looked pretty convincing, but only time will tell if it really works..

I dont know about the infomercial stuff but brazing can be really really strong. The first DP i made was 18g steel and I brazed all the joints on it. I worked on the car its on now the other day and its still holding up fine and looking really ugly A better example would be a brazed bike frame. DAMN strong structure made with lots of joints where the connected metals were not melted.

 

I found myself watching that stupid infomercial too...I think the stupid monotone bitch that talks on there somehow hypnotizes you to keep watching it. Would I buy it? Hell no.

 

in for answers

 

The bike frames are an example of a joint getting strength from its design, as much as from the brazing. Typically, brazing is only used to seal a joint, filling only minimal gaps. What I mean is that these bikes that are brazed will have socket joints, not butt joints.

Also, they boast tensile strength of this alumaloy. I wonder if this was done on a joint, or whether they just took a solid piece of alumaloy and tested it.

Would I use it to fix an aluminum bowl or something? Why not?
Would I use it on a motorcycle frame or swingarm? Hell no.

ya I see what you mean.

I was curious as to how this would work with welding a bov flange onto a charge pipe, welding together a downpipe and also welding all my IC piping .. ?

Well, if you have a welding machine, I'd say use it. But if all you have is this stuff, I'd imagine it can be done, but will look like crap and be pretty difficult to do.

 

I bought this stuff years ago. I was able to get it to bond with very thin metal, but could never get to to bond with anything over 5mm.

 

I tried to make a catchcan with this crap, didnt work.

thats interesting. because if you watch the infomercial they "try" to chisel a big drop of the alumaloy off of a sheet of metal and they "supposedly" can't chip it off lol. But the infomercial is really convincing since they bond everything with that shiet

 

I have also tried it.. didnt work for ****!

 

The video on tv is very intriguing, but I could tell that the person performing the demos was quite experienced with it. That was pretty evident when he took one swipe and filled a huge hole in the bottom of the aluminum can.

You guy need to remember that there's a reason people spend thousands on welding equipment, and welding wires... it's not because they just like spending money. A quick fix is just that... I'd not trust this stuff any more than I would JB Weld.

 

Yeah, I bought it and tried it. I fixed aluminum cans like crazy. (The thin stuff melts under a torch) But the stuff was worthless for trying to join charge pipes. I used half a kit just running a bead around a single pipe, then the joint simply split when I put load on it.

on me for thinking it might work.
