Silicon Metal 3303 2202 for Aluminum Alloy Production and Industrial Chemical Applications

Two grades cover a wide stretch of industrial demand. Silicon metal 3303 carries Si 99.37% with iron, aluminium and calcium each held at or below 0.3%, 0.3% and 0.03% — the economical pick for aluminum alloy production. Step up to 2202, at Si 99.58% with impurity caps of 0.2%, 0.2% and 0.02%, and the same material serves industrial chemical applications where cleaner chemistry pays. ZhenAn casts both grades at its Henan works and ships them as lump, sized to the furnace or reactor that receives them.

Both grades descend from the same smelting line, so a plant that runs 3303 in the melt shop and 2202 on the chemical side keeps one document trail — one COA format, one sampling discipline, one commercial contact — across the whole program.

Lump sizing follows the site standard of 10–50 mm at 90% minimum, with other fractions such as 10–100 mm available against agreed tolerances. Every released lot carries a certificate of analysis.

• Aluminum alloy production: silicon addition to Al-Si melts, where 3303 is the volume grade.
• Industrial chemical applications: 2202 as feedstock where lower Fe and Ca protect downstream yield.
• Master alloy houses blending precise silicon loads.
• Chemical processing lines consuming lump directly or after milling.
• General metallurgical programs needing certified-grade silicon.

1. Split the tonnage by grade — melt-shop volume versus chemical-line volume.
2. Confirm lump sizing per receiving furnace or mill feed.
3. Choose packing: 1 MT big bags, roughly 20–25 MT per 20' container.
4. Fix the commercial frame: FOB, CFR or CIF, port named.
5. Settle payment through L/C, T/T or Western Union.
6. Require the COA per lot and decide on third-party inspection.

To put a quotation together, please share the following details:

• Grade split: how the tonnage divides between 3303 and 2202.
• Lump fraction per receiving line, plus packing preference.
• Volume per dispatch and the discharge port.
• Any laboratory-sample need alongside the commercial offer.
