What is Manganese?
Manganese (CAS 7439-96-5), abbreviated Mn and commercially known as Cutaval, is a transition metal supplied in refined elemental form for industrial and specialty applications.
Where is Manganese used?
- Steelmaking and alloy production: added to control sulfur content, improving hardness in structural steel, stainless steel and high-strength alloys
- Agricultural feed and fertilizer: micronutrient additive correcting soil and animal deficiencies that affect crop yield and livestock health
- Water treatment: manganese-based systems oxidize dissolved iron and control biological fouling in municipal and industrial supplies
- Personal care and pigment manufacturing: colorant precursor and catalyst component in oxidative formulations
- Electrolytic manganese metal is the most traded form.
Commercial specifications
- Purity grades from technical to high-purity electrolytic
- Electrolytic manganese metal meets specifications for steel and battery-grade applications
