Classification
| AWS class | ER4047 |
|---|---|
| EN ISO class | EN ISO 18273 (2016) : Al 4047 - AlSi12 |
Purpose
- High-silicon (12% Si) Al-Si solid TIG rod for joining aluminum-silicon castings above 7% Si.
- Continuous-rod version of ALU 4047, for manual TIG process.
Why it works
Same principle as its MIG-wire twin (ALU 4047) — silicon near the Al-Si eutectic for maximum fluidity — in TIG-rod form for higher productivity on serial production of high-Si castings.
Fields of application
- Joining aluminum-silicon castings above 7% Si.
- Higher-volume semi-automatic production than the ALU 4047 TIG-rod process.

Equivalence refers to the classification (AWS / EN ISO), not to product identity. In applications with a qualified procedure (WPS), validate the substitution before use.
Base metals
G-AlSi10MgG-AlSi12
Advantages
- Highest fluidity in this datasheet — suitable for very-high-Si castings.
- Ideal for positional, root and precision work (where MIG wire cannot reach).
Limitations
- Lowest ductility in this datasheet (A5 5%) — even lower than the ALU 4047 rod (A5 8%).
- With Si content, the weld doesn't anodize to the same tone as the base metal.
