Our Silicon Metal portfolio includes mainstream grades for aluminum alloying, silicone chemistry, foundry, and general metallurgical use. Backed by in‑house R&D, certified systems, and multi‑site manufacturing, we deliver stable composition, consistent sizing, and reliable lead time across 553, 441, 421, 3303, 2202, and 1101.
A versatile choice for aluminum casting and alloying; typical Si ≥ 98.5% with controlled Fe/Al/Ca. Available in lump and crushed sizes for efficient charging and low dust.
Lower impurity levels than 553 help tighten melt quality and reduce inclusions; suitable for Al‑Si master alloys and selected silicone intermediates.
Reduced Fe and Al support higher‑purity aluminum alloys and organosilicon routes where impurity carryover must be minimized.
Balanced impurities for chemical and metallurgical applications that demand uniformity without premium‑grade costs.
Higher‑purity metallic silicon for organosilicon synthesis and processes sensitive to metallic contaminants; consistent low Fe/Al/Ca supports yield and cleanliness.
For demanding processes requiring very low impurities; available upon request with enhanced inspection and certification.
Si metal improves fluidity, castability, and strength in Al‑Si systems, reduces shrinkage, and supports fine eutectic structures. Compatible with AlSi master alloys, AlTiB grain refiners, and AlSr modifiers.
Grades 441/421/2202 help protect catalysts and reduce side reactions in silane and silicone monomer synthesis. Uniform sizing supports smooth furnace charging.
In steelmaking and non‑ferrous foundries, this material acts as a deoxidizer and alloying element. Grades 553/441 provide cost‑effective performance.
Where process routes permit, high‑purity grades (2202/1101) serve as precursors prior to further purification.
Standard lumps (10–100 mm) and tailored fractions match furnace requirements, minimize fines, and improve charge homogeneity.
Powdered material (0–10 mm; 100–200 mesh on request) supports blending, briquetting, or high‑surface‑area reactions.
Options include 1 MT jumbo bags with liners or 25 kg bags on pallets. Units are moisture‑protected and labeled with grade, batch, and net weight; custom palletizing and export documents are available.
Supply is managed under IATF 16949:2016, ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and Energy Management System frameworks.
Each batch receives spectral and impurity analysis in accredited labs, supported by reduction and muffle furnace equipment. Certificates of analysis accompany shipments.
Raw materials, production records, and outbound batches are linked end‑to‑end for consistent supply and rapid root‑cause analysis.
Four production bases, including the 133,333 m² Anhui plant and the Harbin provincial R&D center, support large‑volume distribution alongside alloying additives.
Eight distribution centers in Fujian, Jiangsu, Chongqing, and Guangdong enable fast national coverage and exports to ~40 countries, shortening lead times.
We maintain stable cooperation with leading aluminum groups and participate in major exhibitions. As a drafter of the national standard for aluminum alloy additives, we bring deep metallurgical know‑how.
Choose 553/441 for general alloying and foundry, 421 for tighter impurity control, and 2202/1101 for high‑purity chemical routes. Align impurity ceilings with downstream tolerance.
Higher purity can lower side reactions and inclusions but carries a premium. Assess total process cost, slag rates, and yield gains.
Match size distribution to your charging systems to reduce dust and segregation. Our team can recommend sizing for melting profiles or reactor kinetics.
Pair Si metal with AlSi, AlFe, AlMn, AlTi, and AlCu master alloys to reach targets quickly and reproducibly.
Use AlTiB grain refiners and AlSr modifiers to optimize microstructure in Al‑Si castings.
Refining and degassing fluxes support hydrogen removal and inclusion control for cleaner melts.
Share your target grade (e.g., 553, 441, 421, 2202), size range, annual volume, and destination port to receive a tailored price and lead time. Technical data sheets and samples are available on request; contact us to discuss your process and secure consistent supply.
