Brazing Materials

Phosphorus Copper Brazing Filler (BCuP)

Phosphorus Copper Brazing Filler (BCuP) is mainly used to bond the base material of copper and copper alloys and is also used for brazing Tungsten and Molybdenum. In the case of Phosphorus Copper Brazing Filler (BCuP), it is not necessary to use a separate FLUX because of phosphorus (P) that has self-fluxing properties. In addition to the standard Phosphorus Copper Brazing Filler (BCuP) specified by KS and JIS, YOOCHNAG METAL IND. is producing bar-type and ring-type of Phosphorus Copper Brazing Filler (BCuP) that reduces cost and supplements and improves material properties.
