Aluminum Brazing Rods: Follow Up

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!
