Copper & Silver Phosphorus Brazing Alloys
Also known as BCuP alloys (Silverphos, Phoscopper, etc.), these are used to join copper or brass to copper or brass, and are incompatible with the joining of ferrous base metals. The brazing alloys in this group have a wide variety of characteristics, compositions, and melt/flow temperatures. When joining copper to copper, the BCuP alloys can be brazed without a flux. When joining copper or brass to brass, a flux is required. Copper –Phosphorus alloys are available in wire, rod, and preforms.
