ER4047 .030 MIG Aluminium 16 lb Spool Welding Wire Blue Demon

Description

ER4047
Alloy type A5.10  Aluminum and Aluminum Alloy Welding 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
