Low Fuming Bronze (LFB) Bare Rod

Harris® 15 low fuming bronze is considered a “braze-welding” alloy as this copper/zinc alloy exhibits minimal capillary action during brazing. This limits joint design primarily to lap, tee, and butt joints. Butt joints require some edge preparation typically incorporating beveled edges to provide a location for filler metal to be applied and to ensure alloy penetration to the joint root. LFB was developed primarily to braze steel and some cast iron grades including malleable and grey iron. It can be used to join copper but due to its elevated melting temperature care must be taken during brazing to avoid overheating or melting the copper. It is used with the oxy-fuel process. These alloys are bare. Conveniently packaged for point-of-purchase display.
