The Copper-flo™ filler metals are recommended for the flux-less brazing of copper most commonly for joining tubes and pipes in heating, refrigeration, air-conditioning and heat exchanger components. They have lower ductility than the silver-copper-phos products. Copper-flo™ filler metals should not be used on nickel or iron containing metals, including all grades of steel, because a brittle joint will result.Information provided by Johnson Matthey Metal Joining |
