Harris 015FC50 3/32″ X 36″ X 10 LB PKG Low Fuming Bronze

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 flux-coated.

White Low Fuming Bronze Flux Coated Welding Alloy Rod has flux coating that provides superior wetting action with no objectionable fuming. It finds application in braze welding of steel, cast iron, copper and can be used with standard oxy-fuel torches. It features brazing temperature range of 1670 – 1750 deg F and has maximum tensile strength up to 65 ksi. Porosity-free deposits yield excellent color match to the yellow brasses.

Features and Benefits

• Clean braze area
• Remove all rust, oil and grease
• Heavy sections should be beveled
• The alloy should be applied by a brazing technique with a neutral flame
• When applying the bare rod, use a neutral flame with Harris 600 flux
• Flux residue should be removed by wire brushing with hot water
• 1670 – 1750 deg F brazing temperature range
• Flux coating provides excellent wetting action with no objectable fuming
• Porosity free deposits
• Good machinability
• Color matches yellow brass
• 1630 deg F solidus temperature
• 1650 deg F liquidus temperature
• Neutral flame shielding gas

Typical Application:  Braze welding steel, cast iron and copper. May be used with standard oxy-fuel torch.
