Description

TIG Welding Wire – Aluminium – 4043 – 1.6mm, 2.4mm, 3.2mm (5kg Packs)

Product Overview:

Aluminium TIG welding wire – 4043 is a silicon-alloyed (5% Si) filler rod widely used for TIG (GTAW) welding of aluminum and aluminum alloys, particularly those in the 6xxx series (such as 6061 and 6063). Known for its excellent flow characteristics, low melting point, and resistance to hot cracking, ER4043 delivers smooth, bright welds with minimal spatter and excellent corrosion resistance.

This wire is ideal for applications where appearance and strength are both important, including structural aluminum, automotive work, aluminum boat building, and general fabrication.

Available Diameters (All in 5kg Packs):

1.6mm
2.4mm
3.2mm

Key Features:

✅ High Fluidity – Excellent puddle flow and weld penetration
✅ Bright, Smooth Beads – Minimal discoloration and excellent finish
✅ Crack-Resistant Silicon Alloy – Reduced risk of hot cracking
✅ Excellent Feedability and Arc Stability
✅ Ideal for Heat-Treated Aluminium Alloys
✅ Vacuum-Sealed in 5kg Tubes – Moisture and contamination protection

Applications:

Automotive aluminum body and chassis repair
Marine and boat hull fabrication
Bicycle frames and alloy tubes
General aluminum structure welding
Heat exchangers, piping, and storage tanks
Aerospace and trailer manufacturing

Compatible Base Materials:

6061, 6063, 3003, 5052, 7005 (non-heat-treated or solution-heat-treated alloys)
Not suitable for welding 5xxx series with >3% magnesium (use 5356 instead)
