Pure-copper brazing fillers (AWS BCu-1 / BCu-1a) are widely used for low-carbon steel, alloy steel, stainless steel, cemented carbide tools, pure copper and partial nickel-base alloys. Suitable for dissimilar joints such as steel-to-carbide and steel-to-copper.It features good wettability, flowability, excellent ductility and toughness for withstanding strong impact and vibration. Very high melting temperature yields outstanding electrical and thermal conductivity. Widely used in vacuum brazing process, protective atmosphere furnace brazing process, gas flame brazing for certain situations.
