Electrode for welding aluminum forging alloys and aluminum cast alloys. The weld deposit consists of an Al-alloy with 5% Si and is sufficient for almost all cast alloys.
In case of alloys with higher Si-content, the Si-content in the weld deposit increases as well.
Suitable for following base materials:
G-AlSi 7, AlSi 5 Mg
