Sifcupron No17 is a free-flowing copper phosphorus alloy rod, containing a nominal 7% phosphorus. Its good electrical conductivity and corrosion resistance make it ideal for copper tubing, switchgear, motors etc. When brazing copper, it has a self-fluxing capability but Sifsilcopper flux is required when used to join brass or brass to copper. Not suitable to braze iron-containing materials like carbon or stainless steel or nickel-containing materials. Suitable for use in heating and ventilation industries, shipbuilding, and offshore processes and industries.
