QuAlMg4,5Mn TIG Welding Wire – Aluminium AlMg4.5Mn / ER5183 (3.3548)
QuAlMg4,5Mn TIG Welding Wire – Aluminium AlMg4.5Mn / ER5183 (3.3548)
QuAlMg4,5Mn is the strongest wire of the AlMg range: EN ISO 18273 S Al 5183 (AlMg4.5Mn) · AWS SFA-5.10 ER5183 · material no. 3.3548. Alongside 4.8 % magnesium it contains around 0.9 % manganese — and that manganese is the difference: it raises the tensile strength of the weld metal to 280 MPa and stabilises the microstructure.
This makes QuAlMg4,5Mn the wire for load-bearing AlMg structures where the seam has to be as strong as the sheet next to it — for example on AlMg4.5Mn itself, the standard material in shipbuilding and vehicle construction.
Recommended base materials
- AlMg4.5Mn, AlMg2.7Mn, AlMg3, AlMg5
- AlMgSi alloys: AlMgSi0.7, AlMgSi1, AlMgSiCu
- AlZn4.5Mg1
- Casting alloys: G-AlMg3, G-AlMg5
Typical applications
- Load-bearing joints on AlMg4.5Mn — shipbuilding, vehicles, vessels
- Repairs where the seam has to carry the full sheet strength
- Pressure vessels and tanks in AlMg alloys
- Joints on AlZn4.5Mg1
Properties and advantages
- Highest strength of the AlMg range: Re 130 MPa · Rm 280 MPa · A 18 % — with high elongation at the same time
- The manganese content stabilises the microstructure
- Identical-type to AlMg4.5Mn, the shipbuilding standard
- Shielding gas argon; post-processing material-typical
TIG advantage: For larger aluminium structures away from the laser — Ø 1.0–3.2 mm, considerably higher deposition per layer.
TIG form: for manual repair welding.
