ABSTRACT:
The invention relates to low-nickel copper alloys to be used as brazing filler metals, which alloys also contain phosphorus, tin and possibly small amounts of manganese. The alloys are produced by means of atomization methods. Their advantages are low liquidus temperature and narrow mushy zone, high joint strength and good corosion properties. The alloys are cadmium free and economical in price and they are mainly used for brazing copper and its alloys.
