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

  

Alloy type A5.10 Aluminum and Aluminum Alloy Welding Electrodes and Rods. 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.
