RBCuZn-C (Low Fuming Bronze FLUX) Gas Brazing Rods Blue Demon

Low fuming bronze (flux coated) is
a general-purpose, copper base alloy brazing
rod used extensively for gas brazing steel,
copper alloys, cast iron, nickel alloys and
stainless steel. Its low fuming characteristic
and good mechanical properties make this
alloy a widely used general-purpose product.
Preheating is recommended for some
applications and a bronze brazing flux is
required if the rod is not coated. This brazing
rod has a low melting point making it easily
machinable and excellent for sheet metal
work. This alloy also possesses high tensile
strength and good ductility.
