Customer Questions & Answers

can i use a propane torch & do I need flux ?

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?
Asked by: Johnny
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. Enjoy

why won't this stick to my aluminum timing chain cover? this junk just dripped off. wasn't even close to sticking. wasted my money on this
Asked by: Doc
Sounds like your timing chain cover wasn't properly cleaned and prepped. Also that you didn't heat the cover itself up enough. There's a few good how to videos on you tube. I would check them out then try the brazing again. Good luck.

AL3 Aluminum Brazing and Welding Rods is rated 4.2 out of 5 by 6.
Rated 3 out of 5 by from works ok Bought these because i was out of hts2000. The rod worked ok, but imo, hts2000 is far better for ease of use, tinning, repair.

Rated 3 out of 5 by from 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 4 out of 5 by from 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!

Rated 5 out of 5 by from 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 5 out of 5 by from 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.

Rated 5 out of 5 by from Great for small jobs These are hard to find in other stores, HD was the only store locally that stocks them. I used them to fix a broken strap on an aluminum chase lounge chair. Overall these worked well and I was happy with the end result. Just ensure that you clean and prep the area thoroughly of this won't stick. I used a propane torch to heat everything but wish I had used a MAPP torch as these rods seemed to need a lot of heat. Now, I always keep a few of these in my toolbox just in case.
