Harris® 15 low fuming bronze is considered a “braze-welding” filler metal as this copper/zinc filler metal 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 filler metal 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 filler metals are flux-coated. Conforms to the EU Reach & RoHS directive. Conveniently packaged for point-of-purchase display.
