Fundamentals of Brazing #3: Fluxing the Parts

[@tjvanderloop1686]

A chemical compound has three uses with different metal types: 1- Copper to copper-flux (phosphorous bearing filler metal & flux), 2-Copper to steel-flux (a phosphorous-free filler metal & flux), 3-Copper to brass (Phosphorous filler metal & flux applied as a paste or a filler compound as a wire filler). Great information as usual, keep up the good work on KZbin. T J (Tom) Vanderloop, Author, AWS Member & Technology Instructor

Well, a lot of bronze brazing rods are sold coated in flux, so you can sometimes.
