Produts Description
The content of phosphorus is the key factor to determine the melting range and performance. It can be used as self-fluxing in the welding between red coppers. It is free flowing and no need adding flux. But it will need brazing flux when join brass and bronze. We can provide various composition ratio of phosphorus copper filler metal according to clients' demand.
