I have loose rivets on my alum. boat. I would rather braze them instead of going cheap with epoxy. Do i need to use a flux & should I use maap gas with a special torch tip or can i just use a regular plumbers propane torch?

Here is an excellent YouTube video on using the product.
If you look around YouTube there are several videos showing people 'welding' holes, tears and aluminum engine parts.

“ These rods are mostly made of zinc and have a melting temperature lower than that of aluminum. So they can be used for brazing or braze welding aluminum together. The alloy does not require additional flux when used on aluminum as the zinc content will help wet the surface and remove aluminum oxides. Additional brazing flux may be used. These rods should be used by heating the work piece (torch, induction, etc) and are not suitable for use with stick welding. "

Rated 4.3 out of 5 by 4 reviewers.
Rated 3.0 out of 5.0 by Requires flux to work well, expensive for just two rods If you use these rods by themselves, they will work, but they will not adhere to the aluminum very well. I did several tests and although the joint held without stress, I was able to break the test joint apart fairly easily with some pliers. The 'solder' produced by the rods just doesn't adhere well to the aluminum, no matter how well I brushed or cleaned the surface. After watching a YouTube video by a company that sells aluminum brazing flux and rods, I tried some powdered brazing flux with these rods to see if the flux helped. Massive improvement. The flux turned to liquid when the aluminum was hot enough, and when the brazing rod melted on the joint, the flux pulled it into the joint with capillary action. The resulting brazed joint had a smooth surface, like a smooth weld, and the solder flowed on both sides. The resulting joint using powdered flux was so strong that I was unable to tear it apart. The aluminum tore around the joint while the brazing held strong. So when used with flux, these rods produce a very strong joint. If you need to braze aluminum in a pinch and can't wait to for flux and more economical rods to arrive in the mail, these rods will work, but not very well. I highly recommend getting some aluminum brazing flux, as it makes a huge difference. While these only costs $4, $2 per brazing rod is quite expensive, so if you are going to the effort of getting some brazing flux, you can also get a pack of a few dozen rods from the same source for just a few dollars more.

Rated 5.0 out of 5.0 by works well, saves money I used this rod with MAPP gas to repair a cracked bolt hole on a aluminum turbo blow off valve for my car. Just make sure to thoroughly clean the surface with a stainless wire brush to rid of oxidation right before heating up the piece to be worked on. Also make sure to keep the flame moving all around to allow equal heating so it adheres properly. Flux is not needed but will be helpful if you are connecting joints due to the capillary action of the flux. January 22, 2016
Rated 5.0 out of 5.0 by works great suggest viewing some you tube videos on how to use it this saved me numerous times. Its harder then alluminum so it works really well lets say for a bike when the rear wheel mounts are wore out and you cant tighten down your wheel axle anymore. make a mold using sheet metal and melt this stuff in it and you got a repair thats stronger then taking it to a weld shop.

Rated 4.0 out of 5.0 by Good Product Got this product to use to build frames for display panels instead of buying the mig conversion kit for my arc welder and it has been performing well. Took a little time to get the hang of using it but now that I have it works great! May 1, 2013
