Typical applications are the joining of ferrous, nonferrous and dissimilar metals and alloys with close joint clearances.
Excellent replacement to cadmium containing alloys. Broad application in furnace brazing.
Standard forms of #A-45 are brazing wire, brazing strip, 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) Z49.1, "Safety in Welding and Cutting". For more complete information, refer to the Material Safety Data Sheet for #A-45.
