  • LFB (bare low fuming bronze) is a general-purpose oxyacetylene/brazing rod used for joining various ferrous and non-ferrous metals such as carbon steel, copper alloys, cast iron, malleable iron, stainless steel, and some nickel alloys. Mechanical and physical characteristics include ductility, machinability, high strength, free-flowing with good tinning action and a low melting point (1630°F)
  • A “must-have” filler metal for every machine shop, LFB is excellent for building up worn surfaces or large areas where successive layers must be added; galvanized parts can be brazed without damaging the zinc coating. The precise balance of copper and zinc along with alloying elements of tin, iron, manganese, and silicon produces weld deposits that can be easily machined but work-harden once put into service; high silicon level promotes low fuming

RBCuZn-C - LFB Bare Bronze Brazing Rod is a Copper -Zinc Brazing Alloys suitable for gas-flame brazing, high-temperature brazing of copper and copper alloys, nickel, cast iron, and hard alloys. During oxy-acetylene brazing, heat with oxidized flame quickly can lessen the evaporation of zinc and prevent porosity from over -oxidization. The optimum joint gap is 0.025-0.1mm. Flux is also necessary to obtain a good brazing seam.
