MIG-MAG solid wires range for aluminium alloys

FILALU AlSi5 is a 4043 type aluminium solid MlG welding wire, supplied precision layer wound, depositing Al-5Si weld metal.

Product Advantages

✔ Excellent weldability 
✔ Good mechanical characteristics

Suitable for use with Ar, or Ar+He mixed shielding gases.
FILALU AlSi5 is used for welding of aluminium and aluminium alloys with a silicon content up to 7% in both wrought and cast form. Suitable for Al-Mg-Si alloys series 6000 and for dissimilar welding such as 6000/1000 or 6000/3000.

Due to its Si-alloying the weld pool is readily controllable. The weld is not sensitive for cracking and the surface is bright. Solid wire that deposits a 5% Si alloy.
Particularly suitable for welding Anticorodal 163 and 11 alloys.

It meets the classifications:

  • EN ISO 18273: S Al 4043 (AlSi5)
  • AWS A5.10: ER 4043
