Harris 15 Low Fuming Bronze is copper- zinc braze rod 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 the elevated melting temperature care must be taken during brazing to avoid overheating or melting the copper. It is used with the oxy-fuel process.
Harris 15 is considered a “braze-welding” rod 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. To braze; heat the base metals to brazing temperature and manually deposit the rod along the joint.

• Braze welding steel
• Cast iron
• Copper
• May be used with standard oxy-fuel torch.
