Arcflow ER4047 Aluminum MIG Welding Wire is a premium aluminum-silicon alloy filler wire developed for MIG (GMAW) welding of aluminum and aluminum alloys. It conforms to AWS A5.10 ER4047 standards, ensuring consistent weld quality and reliable performance in demanding fabrication environments.
ER4047 welding wire contains approximately 11–13% silicon, which significantly improves weld pool fluidity and reduces the melting temperature compared to standard aluminum filler wires. This high silicon content helps minimize thermal distortion and reduces the risk of hot cracking during welding.
Due to its low melting point and narrow solidification range, ER4047 provides smooth metal flow and excellent bead appearance, allowing welders to produce high-quality weld joints with minimal shrinkage and porosity.
Arcflow ER4047 aluminum MIG wire is suitable for welding aluminum-silicon and aluminum-magnesium alloys, including common alloys used in fabrication and casting components. It delivers stable arc characteristics, smooth wire feeding, and minimal spatter, ensuring efficient welding performance and consistent weld strength.
This aluminum welding wire works effectively with 100% argon shielding gas in MIG welding processes, providing strong weld deposits and excellent corrosion resistance.
ER4047 MIG welding wire is widely used in automotive parts, heat exchangers, aluminum structures, transportation equipment, and industrial fabrication, where high weld quality and crack resistance are required.
