1. What is Silicon Metal 553?​

Grade code meaning:​
First digit = main impurity level of Fe​ (iron) → 5​ means Fe ≤ 0.5%
Second digit = main impurity level of Al​ (aluminum) → 5​ means Al ≤ 0.5%
Third digit = main impurity level of Ca​ (calcium) → 3​ means Ca ≤ 0.3%
Typical composition range:​
Si ≥ 98.5% (rest is Fe, Al, Ca and trace others)
Fe ≤ 0.5%, Al ≤ 0.5%, Ca ≤ 0.3%
Uses:​
Aluminum alloy production
Chemical industry (silicones, silicones polymer precursors)

Lower‑purity foundry applications

 

What is the price of silicon metal 553?

Price range (Dec 2024 / early 2025, indicative USD/MT CFR China major ports):​
Roughly USD 1,800 – 2,200 / metric ton, depending on quantity, delivery terms, and market trends (e.g., raw material costs, electricity prices in smelting regions, export taxes). Prices can shift weekly with supply/demand and Chinese export policies.

 

2. What is Silicon 3303/ Silicon Metal 3303?​

Grade code meaning:​
First digit = Fe ≤ 0.3%
Second digit = Al ≤ 0.3%
Third digit = Ca ≤ 0.03%
Typical composition range:​
Si ≥ 99.0–99.3% (higher purity than 553)
Fe ≤ 0.3%, Al ≤ 0.3%, Ca ≤ 0.03%
Uses:​
Higher‑grade aluminum alloys
Organosilicon chemicalsSome steel deoxidation applications requiring lower impurity levels

Electronics or specialty alloy markets where Fe/Al/Ca must be minimized

 

What is the price of silicon 3303? What is the price of silicon metal 3303?

Price range (Dec 2024 / early 2025, indicative USD/MT CFR China major ports):​

Typically USD 2,300 – 2,700 / metric ton, reflecting the higher purity and stricter impurity controls compared with 553. Exact price depends on order size, shipping term, and market dynamics.
