The L-CuP6 brazing alloy is very well suited for brazing copper alloys (e.g., tin bronzes or brass) as well as pure copper. It can be used without flux when brazing pure copper parts. The phosphorus is sufficient to create a reducing atmosphere. For all other applications, FH10 flux (silver solder paste) should be used. The FH10 flux is available together with a robust brush for application in combination with the brazing alloy rods. <\/p>\n

L-CuP6 is particularly suitable for copper pipe installation according to DVGW worksheet GW 2.<\/p>\n

However, it is unsuitable for brazing Fe- and Ni-containing alloys.<\/p>\n

CuP6 is also very well suited as a master alloy to specifically introduce phosphorus into copper alloys. In small quantities (max. 0.5%), phosphorus improves the mold-filling capacity (castability) of the melt because it deoxidizes it. In addition, it increases strength. However, excessive amounts of phosphorus make the alloy brittle and should therefore be avoided. To still ensure good formability, the phosphorus content should not exceed 0.35%; for pure casting alloys, it can be up to 0.5%. <\/p>\n

For quantities up to 5 pieces, we offer the rods divided in the middle to provide you with a more favorable price through shipping cost savings.<\/p>\n","protected":false},"excerpt":{"rendered":"
