Harris Products Group, 015FC60B, Brazing Alloy, Flux-Coated, Copper-Zinc, 1.02 lb

Harris® 15 low fuming bronze (LFB) flux-coated is considered a “braze-weld” 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 gray 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. This alloy is flux-coated, eliminating the need for manual flux application.

Features

• Limited joint designs to lap, tee and butt joints, although butt joints require some edge preparation
• Developed to braze steel and some cast iron grades including malleable and gray iron and joining copper
