Solbraze BCuP-2 is a widely used copper-phosphorus brazing rod with zero silver content, making it an economical choice for general copper brazing applications. It is primarily developed for copper-to-copper joints and is self-fluxing on copper, thanks to its phosphorus content.
This alloy provides reliable joint strength where assemblies are not exposed to excessive vibration or movement. It may also be used on other non-ferrous copper-based alloys, provided proper joint conditions are maintained.
When brazing brass or bronze, a suitable flux must be used to ensure proper wetting and joint formation.
