QuAlSi10 TIG Welding Wire – Aluminium AlSi10Mg (3.2383)
QuAlSi10 TIG Welding Wire – Aluminium AlSi10Mg (3.2383)
QuAlSi10Mg is the identical-type filler metal for AlSi10Mg to EN ISO 18273 S Al Si10 (S AlSi10Mg) · material no. 3.2383. With 9–11 % silicon and 0.2–0.5 % magnesium it is matched to the most widely used aluminium die-casting material — and to AlSi10Mg parts from additive manufacturing, which use the same alloy.
The high silicon content makes the weld metal strong (Rm 140 MPa) and the melt flow tight — exactly right for filling cavities, pores and defects in die castings without losing the contour.
Recommended base materials
- Aluminium-silicon alloys with approx. 10 % Si
- AlSi10Mg die castings
- AlSi10Mg parts from additive manufacturing (same alloy)
Typical applications
- Filling cavities and pores in aluminium die castings
- Repair and finishing of 3D-printed AlSi10Mg parts
- Contour corrections on die-casting tools
- Build-ups on housings, brackets, heat sinks
Properties and advantages
- Identical-type to AlSi10Mg — seam and base material behave the same when anodising and reworking
- Highest strength of the AlSi range: Re 70 MPa · Rm 140 MPa · A 4 %
- Tight melt flow — good for near-contour build-up
- Shielding gas argon; post-processing material-typical
TIG advantage: For larger aluminium repairs away from the laser — Ø 2.4 mm, considerably higher deposition per layer.
TIG form: for manual repair welding.
