ER4043
AWS A5.10 ER4043
EN ISO 18273 S Al 4043 (AlSi5)
Description：
An Al-Si alloy welding wire can use where base metal require thermal treatment, mainly 6xxx series alloys. Higher silicon improve fluidity, make it become preferred choices of welders. This product is not sensitive to weld crack, it also can be used on weld forge and casting materials. Welding for 6xxx series alloys.
