Industry Overview & Recent Trends The chromium manganese alloy family, encompassing products such as ferro silico manganese and manganese ferroalloy , is critical in modern metallurgy, casting, and advanced manufacturing. According to the International Manganese Institute (IMnI), global manganese alloy production achieved 21.2 million metric tons in 2023 , while the chromite-manganese alloy sector saw a 6.8% CAGR since 2019 ( IMnI Source ). These alloys enable higher tensile strength, better wear/corrosion resistance, and promote cleaner steel manufacturing (lowering S and P as tramp elements). The main related categories include: Ferro Silico Manganese (FeSiMn) : Used for deoxidizing and alloying steel, providing both Si and Mn addition in one step. Ferrosilicon Manganese (FeSiMn/FSM) : Similar to FeSiMn, but with tailored Mn/Si balancing for specialty steels and foundries. Manganese Ferroalloy : Covers a spectrum, including high-carbon & low-carbon grades for stainless steels, automotive steels, heat-resisting alloys, etc. Manganese Metal : Refined to >99.7% purity, for high-end use in lithium batteries, special alloys, and advanced magnetic materials. 2.
