MIG WIRE 4043 ALUMINIUM 1.6MM (7KG/ROLL)
MIG Wire 4043 Aluminium 1.6mm (7kg/Roll)
Premium ER4043 Aluminium MIG Welding Wire — 1.6mm Diameter, 7kg Spool
Product Overview
Get clean, strong, and consistent welds every time with our ER4043 Aluminium MIG Welding Wire. Engineered for professional fabricators, contractors, and industrial workshops, this 1.6mm wire comes on a generous 7kg roll — reducing spool-change downtime and keeping your production line moving.
4043 aluminium wire is a silicon-alloyed filler metal known for excellent flow characteristics, reduced weld spatter, and a lower melting point compared to other aluminium alloys — making it a top choice for welding cast aluminium and heat-sensitive components.
Key Features
- Alloy Type: ER4043 (5% Silicon Aluminium Alloy)
- Wire Diameter: 1.6mm — ideal for medium to heavy-gauge aluminium welding
- Spool Weight: 7kg per roll — fewer changeovers, less downtime
- Excellent Flow & Wetting: Produces smooth weld beads with minimal spatter
- Lower Melting Point: Great for welding thin sections and reducing cracking risk
- High Purity Aluminium: Consistent feedability through MIG guns and liners
- Reduced Crack Sensitivity: Well-suited for cast aluminium alloys (3xx and 4xx series)
Common Applications
- Automotive aluminium repair and fabrication
- Marine and boat building
- Aluminium casting repair
- General fabrication and structural aluminium work
- Bicycle frame and light-vehicle manufacturing
- HVAC and sheet metal aluminium welding
Why Choose 4043 Aluminium MIG Wire?
Compared to 5356 wire, ER4043 offers superior flow, a smoother finish, and better performance on cast aluminium and heat-affected zones, making it a preferred choice where crack resistance and bead appearance matter most. It is also a strong option for welding dissimilar aluminium alloys.
