Silver brazing paste FB126P, brown paste, with strong activity and longer life and better soldering fluidity than common white silver brazing paste. It can remove fluoride effectively, improve brazing flux's wettability on base materials and permeability, and ensure compact brazing connectors and joints and few residues after soldering together with silver base brazing flux brazing copper, copper alloy, steel, stainless steel and high-temperature alloy at 560~900℃. It adopts torch and induction soldering methods and is suitable for hardware, spectacle frame and cutter industries.
