Manganese Metal Flake – Product Overview

Manganese Metal Flake (electrolytic manganese metal) is a high-purity form of manganese produced by electrolysis of manganese sulfate solution. Our Mn ≥99.7% flakes feature extremely low impurities (C, S, P, Fe, Se, Si) making them the preferred raw material for critical metallurgical and battery-grade applications. The flake morphology ensures rapid dissolution in molten steel and easy handling in chemical processes.

Application Guidelines – Manganese Metal Flake

Manganese Metal Flake is a versatile high-purity material with the following primary applications:

Steel & Superalloys

As a vital alloying element in stainless steel (200-series), wear-resistant steel (Hadfield manganese steel), and HSLA steels. Mn improves strength, toughness, and work hardening. Ultra-low P and S content prevent hot shortness and improve final properties.

Lithium-ion Battery Cathodes

Dissolved in sulfuric acid to produce high-purity manganese sulfate (MnSO4·H2O) suitable for LMO and NMC cathode precursors. The extremely low levels of impurity metals (Fe, Cu, Ni, etc.) are essential for long cycle life and safety of EV batteries.

Non-Ferrous Alloys

Added to aluminum alloys (e.g., 3003, 3104) to increase strength and corrosion resistance. Also used in copper-manganese alloys for damping applications.

Welding & Fluxes

Incorporated into electrode coatings and submerged arc welding fluxes to improve arc stability, deoxidation, and mechanical properties of the weld metal.

Chemical Intermediates

Raw material for manufacturing manganese acetate, manganese carbonate, manganese chloride, and other specialty chemicals used in catalysts, fertilizers, and animal feed.

Typical Addition Rates

In stainless steel production, addition rates range from 6% to 16% depending on the grade. For aluminum alloys, typically 0.5% to 2%. Our technical team can recommend optimal sizing (flake vs. granule) to maximize recovery and minimize oxidation losses.

Frequently Asked Questions – Manganese Metal Flake

Is it possible to entrust a third-party inspection to check the quality before shipment? +

Certainly, we support third-party inspections by internationally recognized quality inspection agencies such as SGS and BV to verify product quality before shipment. The inspection covers product appearance, weighing, dimensions, and chemical composition analysis. The entire inspection process will be documented with photos and written records, which will be provided to you together with the final inspection report. This ensures you have no concerns regarding product quality.

What is the difference between electrolytic manganese flake and ferromanganese? +

Electrolytic manganese flake is pure manganese (≥99.7% Mn) produced via electrowinning, with very low carbon and impurities. Ferromanganese is an alloy of manganese and iron (typically 65-80% Mn, balance Fe) produced in a blast furnace. Pure manganese flake is used when iron contamination must be avoided, such as in aluminum alloys, certain stainless steels, and battery chemicals.

Can Manganese Metal Flake be used directly for battery cathode production? +

Not directly. The flake is first dissolved in sulfuric acid to produce high-purity manganese sulfate (MnSO4·H2O), which is then used as precursor for cathode materials like LiMn2O4 or NMC. Our 99.7% purity with extremely low transition metals (Ni, Cu, Co) ensures the final battery material meets stringent quality requirements.

What particle size is recommended for aluminum alloying? +

For aluminum melting, crushed granules (2-15 mm or 5-20 mm) are typically preferred over fine powder to minimize oxidation loss and improve recovery. Flakes can also be used but may require longer melting time. We can supply custom-sized material to match your furnace practice.

Do you provide a certificate of analysis with each shipment? +

Absolutely. Every batch of Manganese Metal Flake is tested in our ISO 17025 accredited laboratory, and a Certificate of Analysis (COA) showing Mn, C, S, P, Fe, Se, Si, and other trace elements is provided with the shipping documents. Additional impurity testing (e.g., Pb, Cu, Ni for battery grade) can be arranged upon request.

What is your production capacity for Manganese Metal Flake? +

We have an annual production capacity exceeding 25,000 metric tons of electrolytic manganese metal, including standard 99.7% and battery-grade purity. We can accommodate both containerized and bulk vessel shipments with consistent quality.

Do you offer special packaging to maintain purity and prevent oxidation? +

Yes, for high-purity and battery-grade manganese, we recommend moisture-proof liners, vacuum-sealed bags, or argon-filled drums to minimize oxidation during transit. Please discuss your specific requirements with our sales team to ensure the material arrives in perfect condition.
