High Carbon Silico Manganese alloys are developed under the supervision of highly qualified professionals with precise chemical specifications. Our expertise lies in manufacturing these high carbon alloys and carbon manganese alloys in standard as well as customized form to meet with the drawings and specifications of our esteemed clients.

Silicomanganese (SiMn), a ferroalloy with high contents of manganese and silicon, is made by heating a mixture of the oxides manganese oxide (MnO2), silicon dioxide (SiO2), and iron oxide (Fe2O3), with carbon in a furnace. They undergo a thermal decomposition reaction. It is used as a deoxidizer and an alloying element in steel.

The standard grade silicomanganese contains 14 to 16% of silicon, 65 to 68% of manganese and 2% of carbon. The low carbon grade SiMn has carbon levels from 0.05 to 0.10%.
