Ferro molybdenum can be used in any melting process to add molybdenum to all types of iron and steel, and is supplied in a range of sizes for furnace or ladle addition. The recovery should be substantially 100% if used correctly. For optimum recoveries with ladle additions, ferro molybdenum should be added after the molten metal has covered the bottom of the ladle and before it is three quarters full.
CTOMS Molybdenum also offers Roasted Molybdenite Concentrates in powder as well as in briquettes.

About Ferro Molybdenum
(FeMo) Atomic Numbers 26,42
Ferro Molybdenum is an alloy which is formed by combining iron and Molybdenum. Ferro Molybdenum is a hardening agent and is found in many alloy steels that are heat-treatable. Molybdenum prevents corrosion in stainless steels, and when mixed with iron, the Molybdenum also strengthens and hardens into austenite. Ferro Molybdenum comes in many grades, although predominantly it is produced in just two grades (one for US and one for EU) where the content of pure Molybdenum is between 60% and 75%.
Properties of Ferro Molybdenum
Ferro Molybdenum is an additive to the production process of amorphous metals and will impart several desirable properties into the new alloy. One of the primary benefits of adding Ferro Molybdenum to an alloy is its hardening properties that makes steel extremely strong and weldable as well, for Molybdenum is one of the top 5 melting-point metals. Additionally, the adding of Ferro Molybdenum to an alloy can increase corrosion resistance. Properties of Ferro Molybdenum make it suitable for a variety of protective films over other metals.
Production of Ferro Molybdenum
A large portion of the global Ferro Molybdenum supply is manufactured in China, USA, Russia and Chile. The most basic definition of the Ferro Molybdenum production process would be that the Molybdenum is first mined and then transformed into Molybdenum (VI) Oxide MoO3. That oxide is mixed with iron oxide and aluminium and then reduced in an aluminothermy reaction. Electron-beam melting then purifies the Ferro Molybdenum, or the product can be packaged as-is. 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.
Uses of Ferro Molybdenum
The largest practical applications of Ferro Molybdenum are its use in ferrous alloys, and depending on the molybdenum content range, it is suited for machine tools and equipment, military hardware, refinery tubing, load-bearing parts and rotary drills. Ferro Molybdenum is also used in cars, trucks, locomotives and ships. In addition, Ferro Molybdenum is used in stainless and heat-resisting steels that are employed by synthetic fuel and chemical plants, heat exchangers, power generators, oil-refining equipment, pumps, turbine tubing, ship propellers, plastics and inside acid storage containers. Tool steels, with a high percentage range of Ferro Molybdenum, are used in high-speed machining parts, cold work tools, drill bits, screwdrivers, dies, chisels, heavy castings, ball and rolling mills, rolls, cylinder blocks, piston rings and large drill bits.
Ferro Molybdenum Market
The price of Ferro Molybdenum saw a major upturn since the start of WWII and a subsequent drop since the end of WWII. Today the market remains steady, but with a notable dip when Chile entered the market and continued to expand production of Ferro Molybdenum, as well as other alloys. Another factor in the history of the Ferro Molybdenum market was the breakup of the former USSR, where the single system of mining and production was severely disrupted. Recently, because of an increased Chinese appetite, prices are once again on the increase.
