Silicon Metal 3303 2202 1101 for Metallurgy Aluminum Alloys and Chemical Industry Applications

Metallurgy desks, aluminum alloy plants and chemical industry buyers rarely need one grade in isolation — they need a ladder. ZhenAn supplies that ladder from a single Henan works: 3303 (Si 99.37%) carrying the metallurgical volume, 2202 (Si 99.58%) bridging alloy and chemical duty, and 1101 (Si 99.79%) topping the purity range for demanding chemistry. One smelting platform, one certification discipline, three grades dispatched against whatever the plant schedule calls for.

The portfolio is managed as one program. Each grade is cast, sized and certified on the same line under ISO 9001; each lot carries its own COA with Si, Fe, Al and Ca stated; and dispatch slots can be mixed — one container of 3303 for the melt shop, the next of 1101 for the chemical line — without changing paperwork formats or commercial contacts. Lump moves in 1 MT big bags at 20–25 MT per 20' container.

The ladder is arithmetic and honest: each step up trims every impurity ceiling and adds silicon. Metallurgy lives on the bottom rung, chemistry on the top, and mixed operations order across all three.

• Metallurgy: 3303 for deoxidizing and alloying tonnage
• Aluminum alloys: 3303 and 2202 for Al-Si melts by specification
• Chemical industry: 2202 for general silicon chemistry, 1101 for catalyst-critical routes
• Alloy manufacturing: certified lump for master alloys across grades
• Casting operations: volume charging from the lower rungs of the ladder
