RBCuZn-C (Low Fuming Bronze Bare and Flux Coated)

Alloy Type:

RBCuZn-C Low fuming bronze (bare and 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.
