SiliconManganese alloy is an alloy composed of manganese, silicon, iron and a small amount of carbon and other elements. It is an iron alloy with a wide range of uses and a large output. Silicon manganese alloy is a commonly used compound deoxidizer for steelmaking, and it is also a reducing agent for the production of low carbon ferromanganese and electro-siliconThermal production of metallic manganese.
