Description
Sifcupron No 17-2Ag Copper Phosphorus Brazing Rods – 1.6 mm x 2.5 Kg
A thin-fluxing copper phosphorus alloy with the addition of 2% silver to improve ductility and flowing characteristics.
Highly resistant to corrosion and not subject to dezincification. It is ideal for hot water cylinders, electric motors and also general maintenance work. For brazing copper to copper no flux is needed.
Material to be Welded
This high quality copper phosphorous rod is recommended for use when brazing seams on hot water cylinders, as it is highly resistant to corrosion. Can also be used in the production of electric motors and dynamos. The optimum brazing gap is typically 0.05 – 0.2mm.
Not suitable to braze iron-containing materials like carbon or stainless steels or nickel.
