Lucas-Milhaupt Silvaloy® 45 Brazing Alloy (discontinued **)
Categories:	Metal; Nonferrous Metal; Precious Metal; Silver Alloy; Solder/Braze Alloy
Material Notes:	Silvaloy 45 is the lowest melting brazing alloy available composed of silver, copper, zinc, and cadmium. It is suitable for use on most metals except aluminum and magnesium. It is used for joining steel, stainless steel, copper, copper alloys, nickel, nickel alloys or combinations of these metals. It has a wide acceptance by industrial users, as well as being included in Federal 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 though a capillary. Typical applications are the joining of ferrous, non-ferrous, and dissimilar metals and alloys with close joint clearances.
