4043 Aluminium MIG Wire 0.5kg

ALUWELD 4043 Aluminium MIG Wire — 0.9mm x 0.5kg Spool (For Spool Gun Use)

The ALUWELD 4043 Aluminium MIG Welding Wire is a high-quality aluminium-silicon alloy wire (AlSi5) designed for smooth feeding and clean, consistent welds when used with a spool gun. Its 5% silicon content improves fluidity and reduces hot cracking, making it ideal for general aluminium fabrication and repair work.

Perfect for welding Aluminium 6xxx series alloys (e.g. 6061, 6063, 6082), this wire provides excellent corrosion resistance, low spatter, and bright, clean weld finishes. The 0.5kg spool size is optimized for spool guns, ensuring smooth wire feeding and stable arc performance on portable MIG setups.
