I have my bundle of Aluminum Brazing Rods. There was a problem with shipping so I canceled the order and drove up to Harbor Freight Tools. They carry bundles of Aluminum Brazing Rods for $14.99 not to mention an assortment of other inexpensive gear that comes in very handy for Alcohol Burner construction. Now I'll be honest. This isn't a dig against Harbor Freight Tools. This is just my observatory based opinion. The tooling provided at this store is not high-end. If you are handy at tuning up inexpensive tools, this is a good option for you. Don't expect to get a lot of life out of any hand tools you purchase, unless you are using them every now and then. Just something to keep in mind.
The Aluminum Brazing Rods have a working temperature of 730 degrees F. I'm not a professional welder, but this is more of a soldering temperature than brazing. Nonetheless, they are simple to work with. No flux is needed. Just prep your material with a little 220 or 320 grit aluminum oxide sand paper or a single cut file. I prefer the file because the two mating surfaces will remain flat while they are bonded together. Either way works. I was able to successfully bond two soda cans together. This is perfect for the application intended. I am satisfied with the weld joint. No leaks. I will turn to this for now on. It might not be preferable to all of the "Gram Weenies" out there, but if you are looking for a product to bond two components together with peace of mind, this is the product I recommend. Happy Welding!
