SilverAlloy Cd-35
Nominal Chemical
Composition
INTRODUCTION
Aufhauser SilverAlloy Cd-35 is a modification of SilverAlloy Cd-45 to combine reasonably good brazing properties and lower silver content at the expense of slight elevated temperature (150°F). It has a broader melting range than Cd-45, which is helpful where clearances are wide or not uniform. Unless heating is rapid, care must be taken that the lower melting constituents do not separate out by liquation. Cd-35 is free-flowing and suited for general purpose work. This filler metal contains cadmium.
APPLICATIONS
Aufhauser Cd-35 is used for joining most ferrous and non-ferrous metals. Cd-35 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 in. (0.025 to 0.127 mm) are recommended for proper capillary action.
