Masterweld 4047 Aluminium TIG Filler rod has a higher silicone content than Masterweld 4043. The benefits derived from this alloy are the following;

Benefits of 4047 Filler rod compared with 4043;

  • Lower melting point, making it possible for aluminium brazing applications in addition to welding
  • Increased fluidity(wetting action) and reduced shrinkage.
  • Excellent for welding thinner materials that are required to have leak proof joints
  • Attractive bright weld appearance
  • Significantly reduce hot cracking
  • Slightly higher fillet weld shear strength
  • May be used in applications of sustained elevated temperatures, for example aluminium heat exchangers

Please note

Like 4043 filler rod, 4047 should not be used if you are considering the best colour match after post weld anodizing, as this filler alloy will typically turn dark gray in colour after the anodizing process because of the silicone content.
