What is MA-4043 (ER4043) used for?

MA-4043 (AlSi5, ER4043) is an aluminium-silicon welding wire that prevents solidification cracking at high dilution and with rigid clamping. The MIGAL.CO material calculator recommends AlSi fillers for pure aluminium, AlMn alloys such as EN AW-3003 and EN AW-3103, AlMg1 alloys such as EN AW-5005, AlSiMg alloys such as EN AW-6082 and EN AW-6005A, AlSi cast alloys, and for AlMgSi alloys (EN AW-6060, 6061, 6063) when crack resistance is the priority. Note: AlSi weld metal turns dark grey after anodising and gives no colour match.

  • Classification: EN ISO 18273: S Al 4043A (AlSi5(A)); AWS A5.10: ER4043; material no. 3.2245

Remarks

This alloy is particularly used to prevent solidification cracks in connection with high dilution and clamp conditions. Anodizing gives dark colours and is not recommended. The weld pool is very fluid.
