Key Differences: 553 Vs. 1101 Silicon Metal
The primary distinction lies in impurity content and applications:
•Grade 553: Contains slightly higher levels of tramp elements (e.g., Al ≤ 0.5%, Fe ≤ 0.5%, Ca ≤ 0.3%). It is widely used in cost-sensitive applications like aluminum alloys, where moderate purity suffices.
•Grade 1101: Boasts stricter purity standards (e.g., Al ≤ 0.1%, Fe ≤ 0.1%, Ca ≤ 0.1%). Its low impurity profile makes it ideal for high-performance uses, including organic silicon production and solar-grade polysilicon, where precision matters most.
