Good for brazing dissimilar metals. #45 is the lowest melting brazing alloy available composed of silver, copper, zinc and cadmium. It is suitable for brazing most metals except aluminum and magnesium. It is used for brazing steel, stainless steel, copper, copper alloys, nickel, nickel alloys or combinations of these metals. It has wide acceptance by industrial users, as well as being included in Federal and military specifications on brazing filler metals or alloys. It has a narrow melting range which is not apparent in most brazing operations, making it flow freely through a capillary.

Lowest melting range in joining ferrous, non-ferrous and dissimilar metals with close joint clearance requirement.
Standard forms of Brazeit 45 are brazing wire, brazing strip and brazing preforms.
Safety Information Downloads
#45 contains cadmium and therefore upon heating may produce toxic fumes. It is essential that adequate ventilation be provided so that personnel will not inhale gases and fumes while brazing. The operation and maintenance of brazing equipment or facility should conform to the provisions of American National Standard (ANSI) Z49.1, "Safety in Welding and Cutting." For more complete information, refer to the Material Safety Data Sheet for #45.
