ER4047 (commonly referred to as “718 aluminum” or AISi12) is an aluminum filler metal which contains approximately 12% silicon.
This alloy is commonly used not only in MIG or TIG applications, but also as a general purpose brazing alloy providing a free-flowing filler metal and good corrosion resistance. ER4047 is recommended for welding or brazing aluminum alloys: 1060, 1350, 3003, 3004, 3005, 5005, 5050,
6053, 6061, 6951 7005 and cast alloys 710.0 and 711.0. ER4047 has an approximate melting range of 1070°-1080°F and the post anodizing color tint is grayish-black.
