Description

Harris 4043 is a premium 5% silicon aluminum MIG wire (AWS ER4043), formulated for welding heat-treatable 6XXX series aluminum alloys and repairing Al-Si castings. The silicon content enhances puddle fluidity, improves bead appearance, and delivers a reliable, crack-resistant weld—especially on 6061 and 6063. The wire has a lower melting point and greater fluidity than 5XXX series filler alloys, making it a favorite for out-of-position welds and aluminum fabrication. Suitable for both GMAW (MIG) and GTAW (TIG) processes, it leaves a gray post-anodized color and is commonly used for automotive, trailer, bicycle, and structural welds. Meets AWS A5.10 and ABS standards, and is ISO-certified for consistent quality. Typical tensile strength: 27,000 psi.​
