Product Description
Ferromanganese is a ferroalloy primarily composed of manganese (Mn) and iron (Fe), produced by smelting manganese ore with iron ore and coke in electric furnaces. It serves as a critical manganese source in steelmaking and casting, used for deoxidation, desulfurization, and alloying to enhance metal performance.
- High manganese content (60%-90%), enabling efficient alloying.
- Strong deoxidation/desulfurization: Reduces oxygen and sulfur in molten metal to avoid brittleness.
- Enhances steel toughness and workability by refining grain structure.
- High melting point (~1200-1400°C) for high-temperature smelting.
- Cost-effective vs. pure manganese.
Applications
- Automotive: Engine parts (cylinder heads, pistons), transmission housings (castability, heat resistance).
- Electronics: Heat sinks (LEDs, CPUs) and device casings (thermal conductivity, corrosion resistance).
- Industrial: Pump housings, bearing sleeves (wear resistance).
- Aerospace: Secondary structures (brackets, heat shields) for weight/strength balance.
