SilverAlloy Cd-45
Nominal Chemical
Composition
INTRODUCTION
Aufhauser SilverAlloy Cd-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 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 capillary action. Typical applications are the joining of ferrous, nonferrous and dissimilar metals. SilverAlloy Cd-45 is used for close joint clearances (0.001-0.003 in). This filler metal contains cadmium.
APPLICATIONS
Aufhauser SilverAlloy Cd-45 is used for joining most ferrous and non-ferrous metals except aluminum and magnesium. Cd-45 has good brazing properties and is suitable either for pre-placement in the joint or for manual feeding into the joint. Although lap joints generally are used, butt joints may be used if requirements are less stringent. Joint clearances of 0.001 to 0.005" (0.025 to 0.127 mm) are recommended for proper capillary action.
