Molybdenum metal is widely used in electron tubes, transistors and other electronic rectifier devices, molybdenum oxide and molybdenum are excellent catalysts for chemical and petroleum industries, molybdenum is mainly used for iron and steel industry, which is most of the molybdenum oxide block directly used in steel or cast iron.

Molybdenum is heat resistant to molybdenum crucible, which is mainly used in the manufacture of gun bore, rocket nozzle, tungsten lamp holder and tungsten wire holder. Adding molybdenum into alloy steels can increase the elastic limit, corrosion resistance and permanent magnetism. Molybdenum is one of the seven micronutrients needed in plant growth and development.

Without it, plants cannot survive, a small part of molybdenum is smelted into ferromolybdenum molybdenum foil and used for steelmaking. The content of molybdenum in low alloy steel is no more than 1%, but the consumption in this respect accounts for about 50% of the total consumption of molybdenum. The addition of molybdenum in stainless steel can improve the corrosion resistance of steel.

Molybdenum disulfide is an important lubricant used in the aerospace and mechanical industries. Animals and fish, like plants, also need molybdenum. Molybdenum is one of the essential trace elements in plants. It is used as trace element fertilizer in agriculture.

Pure molybdenum wire is used in high temperature electric furnace and electrical discharge machining, but also wire cutting. Molybdenum sheets are used to make radio equipment and X ray equipment, woodworking band saw machine, molybdenum application in other alloy fields and chemical industry is also expanding. For example, MoS2 lubricant is widely used in lubrication of various kinds of machinery, and molybdenum metal is gradually applied to nuclear power, antioxidant, new energy and other fields.
