Why choose ABRATIG AlMg3 filler metal?
Choosing ABRATIG AlMg3 as a filler metal is an excellent option for welding aluminum alloys containing magnesium, especially those in the 5000 series. Here’s why we use it:
- Perfect for Al-Mg alloys such as 5083, 5754, etc.
AlMg3 is specially formulated to be metallurgically compatible with these alloys, guaranteeing a solid, homogeneous weld, with no risk of cracking or loss of strength.
- Excellent corrosion resistance, even in marine environments
Magnesium enhances corrosion resistance, making this filler metal perfect for marine, outdoor or wet industrial applications.
- Good balance between mechanical strength and ductility
AlMg3 welds offer sufficient strength for structural parts, while retaining a good capacity for deformation without breaking (useful for shock absorption, vibration, etc.).
- Easy to weld, good TIG behaviour
This filler metal has good fluidity, welds cleanly, and limits defects such as porosity. It is also more forgiving than harder alloys such as AlMg5.
