TIG rods range for aluminium alloys

ALTIG AlSi5 is a 4043 type aluminium solid TlG welding rod depositing Al-5Si weld metal. Suitable for use with Ar, or Ar+He mixed shielding gases.

Product Advantages

✔ Weld pool is easy to manipulate due to the Si-alloying

ALTIG 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 joining, e.g. 6000/1000 or 6000/3000.
The weld metal is not sensitive to cracking and the weld deposit surface is bright.
TIG rod that deposits a 5% Si aluminum alloy. Suitable for welding Anticorodal 163 and 11 alloys.

It meets the classifications:

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