FOR ALUMINUM STEEL

I. APPLICATIONS:

NT-Al-12 (4047) 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.
 

II. DESCRIPTIONS:

NT-Al 4047 is more commonly referred to as “718 aluminum” or Al Si 12. It 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. NT-AI 4047 has an approximate melting range of 1070º-1080ºF and the post anodizing color tint is grayish-black.
