MIG WIRE 4047 ALUMINIUM 1.2MM

ER4047 Aluminium MIG Welding Wire 1.2mm | High-Silicon Filler Wire for Aluminium Fabrication

Product Description

Achieve clean, strong, and crack-free aluminium welds with our 4047 Aluminium MIG Welding Wire (1.2mm). Engineered with a high silicon content (approximately 12%), this ER4047 filler wire is the go-to choice for welding cast aluminium alloys, dissimilar aluminium base metals, and applications demanding excellent fluidity and minimal porosity.

Its precise 1.2mm diameter ensures consistent wire feeding, stable arc performance, and smooth bead appearance — ideal for both semi-automatic MIG welding and robotic welding systems.

Key Features

• High Silicon Content (~12%) – improves weld puddle fluidity and reduces hot cracking
• Excellent Corrosion Resistance – suitable for marine and outdoor aluminium structures
• Smooth, Consistent Feeding – precision-drawn 1.2mm wire minimizes birdnesting and feeding issues
• Low Spatter, Clean Finish – reduces post-weld cleanup time
• Wide Compatibility – works well with 3003, 4043, 5052, 6061, and cast aluminium alloys
• Excellent for Thin-to-Medium Gauge Aluminium – ideal for automotive panels, castings, and general fabrication

Technical Specifications

Common Applications

• Automotive aluminium repair & fabrication
• Cast aluminium component welding
• Aluminium heat exchangers and radiators
• General aluminium sheet & structural fabrication
• Marine aluminium welding

Why Choose 4047 Over 4043?

4047 wire contains higher silicon than the more common 4043, giving it superior fluidity and crack resistance — particularly useful when welding cast aluminium parts or joints with high restraint, where reducing hot cracking risk is critical.
