Brass brazing filler metal is mainly used for rapid heating brazing processes such as flame brazing, high frequency induction brazing and resistance brazing. It can braze copper, copper alloys, steel, cast iron, and hard alloys. Before brazing, the grease, oxides and other contaminants on the metal brazing surface must be strictly removed. When brazing, it needs to be used in conjunction with flux to obtain a stable and reliable joint.
