Introduction
Silicon Metal 441 is a widely used grade of silicon metal, known for its stable chemical composition and broad industrial applications. The "441" grade indicates its typical impurity limits:
- Si ≥ 99.0%
- Fe ≤ 0.4%
- Al ≤ 0.4%
- Ca ≤ 0.1%
Compared with grade 553, silicon metal 441 has a higher purity and lower impurity content, making it especially suitable for industries that demand more consistent quality.
