LOW FUMING BRONZE – Bare
LOW FUMING BRONZE – Bare
Low fuming bronze is a popular general-purpose copper-zinc brazing alloy that is commonly used for oxy/acetylene weld brazing of brasses and for brazing copper and copper alloys to carbon and low alloy steels, cast iron, tool steels and nickel alloys. It is machinable and has a high tensile strength with good ductility.
It is not recommended for the joining of copper pipes which carry hot water or sea water. Preheating is required for some applications and bronze brazing flux is required when using bare low fuming bronze rod.
