#A-45T is free flowing, low melting and an excellent substitute to the cadmium-bearing brazing alloys with similar silver contents. #A-45T narrow melt range (75 ºF) makes it suitable for manual or machine feeding into the braze joint. This brazing alloy is best suited for narrow gap filling in the range of 0.001-0.005 inches. #A-45T is particularly useful in brazing steel, copper, copper alloys; and should be used in conjunction with Ultra Flux. The ability to join similar as well as dissimilar metals has allowed for numerous applications in the refrigeration and air conditioning fields.

Typical applications are the brazing of ferrous, nonferrous and dissimilar metals and alloys with close joint clearances.
Good for dissimilar metals with moderate flow characteristics.
Standard forms of #A-45Tare brazing wire and brazing preforms.
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) Z.49.1, "Safety in Welding and Cutting." For more complete information, refer to the Material Safety Data Sheet for #A-45T.
