ER4043 Aluminum Welding Wire | High Fluidity, Low Crack Sensitivity

AWS A5.10 ER4043

Applications:
Used for welding aluminum alloys in industries such as shipbuilding, chemicals, molds, metallurgy, and locomotives.

Features:
THS-Al4043 is an aluminum-silicon alloy welding wire with low sensitivity to thermal cracking, making it suitable for welding heat-treatable base materials. This welding wire offers excellent welding process performance, producing aesthetically pleasing welds with stable arcs and minimal spatter.

 Chemical Composition of Wire:       (Wt. %)

Precautions:

1. The oxide, oil, moisture, and other impurities on the welding joint and wire must be removed before welding.
2. For thick plate welding, preheat the material to 100°C - 200°C before welding.
