Aufhauser SilverAlloy A-45T is a low temperature, cadmium free, filler metal suitable for brazing ferrous and non-ferrous base metals. The lower brazing temperature and free-flowing characteristics makes the A-45T an excellent substitute to the cadmium-bearing filler metals with similar silver contents.
SilverAlloy A-45T narrow melt range (75°F) makes it suitable for manual or machine feeding into the braze joint. The alloy is best suited for narrow gap filling in the range of 0.001-0.005 inches. Typical applications are the joining of ferrous, non-ferrous and dissimilar metals and alloys with close joint clearances. SilverAlloy A-45T is particularly useful in joining steel, copper, copper alloys, and should be used in conjunction with Aufhauser White SilverFlux. The ability to join similar as well as dissimilar metals has allowed for numerous applications in the refrigeration and air conditioning fields.
GENERAL INFORMATIONChemical Composition
Generally, the joint strength using SilverAlloy A-45T will surpass the strengths of the base metals. Strength is a function of the base metals being joined, type of joint, design of joint, joint clearances and brazing procedures. The recommended maximum operating temperature for SilverAlloy A-45T is up to 400°F in continuous service and up to 600°F in intermittent service. For improved corrosion resistance, SilverAlloy A-50Ni2 and SilverAlloy A-40Ni2 are recommended.
