Low-Fuming Bronze

Copper-zinc-tin bare and flux-coated filler metal for braze-welding of steel, some cast iron grades, including malleable and grey iron, and joining copper.


Harris 15 Low-Fuming Bronze (LFB) copper-zinc alloy is designed for torch braze/welding. This alloy can also braze/weld steel, cast iron and copper. It can be used with a standard oxy-fuel torch. LFB is available bare or flux-coated versions.


  • Copper-zinc braze-welding bare and flux-coated rods
  • Exhibits minimal capillary action during brazing
  • Limited joint designs to lap, tee and butt joints, although butt joints require some edge preparation
  • Good machinability
  • Produces porosity-free deposits
  • Color matches yellow brass
  • Corrosion resistance is similar to most high zinc brass alloys. Care should be taken on service conditions where water immersion is involved as dezincification is a potential issue.

Typical Applications

  • Brazing steel and some cast iron grades (malleable and gray iron)
  • Joining copper
