Special Silver-free Alloy Brazing Rod 2.0 x 250mm – 5 Rods

£3.99

You are buying 5 x 250mm lengths of FS70 Brazing alloy Rod. This is a special low cost alloy, containing no silver, but formulated to melt and flow at a similar rate to a 40% silver alloy. For Brass or Brass/Copper joints, this alloy will prove a low cost alternative to silver alloys. Unlike other phosphorus containing alloys, the self fluxing characteristic of such alloys is not as evident, and so a separate flux is always required. This filler metal should not be used to braze iron containing materials like carbon or stainless steels or nickel containing materials as the phosphorus within the filler metal will form brittle, intermetallic phosphide compounds, at the joint interface. The optimum joint gap for brazing is normally 0.05-0.2mm. Composition: Phosphorus – 6.8%; Tin – 7%; Copper – Balance. Conforms to: EN 1044 1999 CP302. Melting range: 650 – 700°C*.
