High-carbon silico manganese

High-carbon silico manganese is an alloy that contains 2.25–2.5% carbon. It’s produced by smelting manganese ore with coke and a quartz flux, or by smelting slag from high-carbon ferro manganese.
High-carbon silico manganese is used as a deoxidizer and alloying element in steel. It can also be used as a hardening agent in aluminum production.
Silico manganese is an alloy of iron, silicon, and manganese. It has a higher silicon content than ferro manganese.

Here are some other things to know about high-carbon silico manganese:

  • Composition: 60–68% manganese, 14–21% silicon, 1.5–2% carbon
  • Production: Produced in large quantities
  • Demand: Demand for these alloys has been on the rise in recent years
  • Health: Dust-free, folded silicomanganese in lumps is not a health hazard when properly handled and stored. Inhalation of manganese vapor oxide fumes can result in acute chemical pneumonia (manganese fever). Prolonged exposure can lead to chronic manganese poisoning with damage to the central nervous system.
