ER4047
Alloy Type: A5.10, ALUMINUM AND ALUMINUM ALLOY Electrodes and Rods
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
