Oerlikon Alurod AlSi5 description: ALUROD AlSi5 is a 4043 type aluminum solid TlG welding rod depositing Al-5Si weld metal. Suitable for use with Ar, or Ar+He mixed shielding gases. ALUROD 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 pool is easy to manipulate due to the Si-alloying. 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.
