Iron alloy is one or more metal or metalloid elements iron alloy composition. Such as silico-manganese (FeMn65Si17) is a silicon (Si) and manganese (Mn) alloys. Ferroalloy is an important raw material of steel and cast steel, steel can improve the physical and chemical properties and mechanical properties of silicon alloy castings factory, machinery, defense, precision manufacturing, household appliances and other industries of the material have become increasingly demanding silicon alloy, for ferroalloy requirements are also increasing. Alloy is an alloy of iron with one or more metallic or non-metallic elements. Ferroalloy is one of the main raw material of steel and mechanical casting industry, used in steelmaking and casting deoxidizer, desulfurizer and alloying additives. Many varieties of ferroalloy, generally in accordance with the elements it contains classified.
