Ferromolybdenum(FeMo) is an alloy formed by combining iron and molybdenum. FeMo is commercially available in the form of lumps. The particle size is 5-50 mm. The molybdenum content is between 50% and 60% .
Molybdenum is one of the most effective alloying agents. FeMo can be added during the production of cast iron and steel. About 80% of it is used to produce various types of steel, such as structural steel, stainless steel, high-speed steel, tool steel, etc.

Production of ferro molybdenum
A large part of the global ferromolybdenum supply is manufactured in China, the United States, Russia and Chile.
Ferromolybdenum production process:
1. First mine molybdenum.
2. Then convert it to molybdenum oxide (VI) MoO3. The oxide is mixed with iron oxide and aluminum, and then reduced in the thermite reaction.
3. Electron beam melting to purify ferromolybdenum.
Typically the resulting alloy will be produced as either small briquettes or as a finer powder. Ferro Molybdenum is usually supplied in either bags or steel drums for shipping.
Applications of ferro molybdenum
Its main use is as an additive for molybdenum in steelmaking. Adding molybdenum to the steel can make the steel have a uniform fine-grained structure. Can improve the hardenability of steel. This will help eliminate temper brittleness.
Combining molybdenum with other alloy elements can produce stainless steel, heat-resistant steel, acid-resistant steel and tool steel. It is also possible to produce alloys with special physical properties.
