ER4047 was originally developed as a brazing alloy (718) to take advantage of its low melting point and narrow freezing range.  It has a higher silicon content than its counterpart, ER4043 which provides for increased fluidity and reduced shrinkage in the weld.  ER4047 produces bright and almost smut-free welds.  This alloy may be used in applications of sustained elevated temperatures.

 

Typical Applications:  welding filler wire
