berAlweld® 4043

berALweld® 4043 Al-Si alloy welding wire, used for weld base metals which can be heat treated, specifically 6XXX series alloys. Due to its relatively weak sensitivity to hot crack, it can also be used to weld forging and casting materials. Silicon enhances the liquidity and is therefore favored by welding workers.

AlSi filler metal for MIG and TIG welding in various applications.

Features:

  • low sensivity to weld cracking
  • Si enhances the fluidity and is therefore favored by welding workers.
  • bright and almost smut free welding.
  • not recommended for anodizing.

Typical Base Materials:

  • AlSi alloys
  • AlMgSi alloys
  • Cast alloys with Si content of max. 7%

Typical applications:

  • Automotive parts
  • bicycle and motor bike frames
  • furniture

Standards:

  • DIN EN ISO 18273 (S Al 3043 (AlSi5)
  • DIN 1732 (3.2245)
  • AWS A5.10 (ER 4043)

Shielding gas (EN ISO 14175:)

  • 100% Ar (I1)
  • Ar / He mixture (I3)
