A phosphor-bronze rod containing 7% tin and suitable for fusion welding of phosphor bronze castings, copper alloys and brass in oxy / acetylene welding for applications such as crack repair in castings. The use of flux is normally unnecessary in most applications, but Sifbronze Flux can be beneficial in aiding flow when used on copper which is dirty or oxidised. Sifphosphor Bronze No 8 is also used for TIG brazing on ferrous, stainless and dissimilar metals. Weldable in all positions and particularly suitable for welding around pipes (with wall thickness >1.6mm).
