Copper, Brass and Bronze Brazing AlloysBrazing Alloys

DESCRIPTION & APPLICATIONS : 

Copper and Brass Brazing Alloys are widely used filler metals for joining copper, copper alloys, steels, cast iron, and cemented carbide. These alloys are suitable for flame, induction, resistance, and furnace brazing applications. Known for their strength, conductivity, and cost efficiency, they are practical alternatives to silver brazing alloys in many industrial and fabrication jobs.
