Product Description
Manganese Metal typically has a purity of ≥95%, produced via electrolysis (for high-purity Mn, ≥99.7%) or silicothermic reduction (for industrial-grade Mn, 95%-98%), and is mainly used as a high-end alloy additive, battery material, and precision industrial feedstock.
- Physical: Silvery-gray, forms oxide film; melting point 1244°C; hard/brittle at room temp, ductile at 800-1000°C.
- Chemical: Reacts slowly with water/dilute acids; oxidizes in air (protective MnO₂ film); high-purity Mn resists weak acids.
- Metallurgical: Enhances alloy strength/toughness; better than alloys at removing O/S from molten steel.
Applications
- Steel Industry (60% of industrial-grade Mn usage)：Adds to high-end/low-alloy steel (boosts toughness by 20-30%); replaces nickel in stainless steel.
- Non-Ferrous Alloy Sector (25% usage): 1-3% in Al/Mg alloys (corrosion resistance); in Cu alloys (precision parts).
- Battery & Electronics Industry (10% usage, fastest-growing sector): Ultra-high-purity Mn for Li-ion battery cathodes (EVs, storage); magnetic materials. magnetic materials.
