#A-54N

#A-54N is a silver brazing alloy suitable for furnace brazing due to its low zinc content. Its broader melting range (250 ºF) is helpful where clearances are not uniform. During melting, #A-54N passes from the solid state to a mushy or plastic state and progressively to a liquid. If heated slowly through this plastic state (1325-1575 ºF) the liquid portion may flow from the solid portion. This causes a separation of the alloy into a low temperature melting (solid) portion. This phenomenon is called liquation. The high temperature melting portion will melt only above the normal brazing temperature of #A-54N. For this reason, #A-54N should be heated rapidly through the melting range.

Applications

Typical applications are the brazing of ferrous, nonferrous and dissimilar metal and alloys.

Low zinc suitable for furnace brazing. Good for elevated temperatures to 700°F. Used for carbon assemblies.

Available Forms

Standard forms of #A-54N are brazing wire, brazing strip, and brazing preforms.

Safety Information

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-54N.
