Molybdenum is a silvery-white metal with one of the highest melting points of any element and one of the lowest coefficient of thermal expansion amongst metals. Its name is derived from the Greek word “molybdos”, meaning lead.
It is very hard and tough, although softer and more ductile than tungsten. Chemically, it is very stable, although it will react with acids.
Molybdenum product uses
Molybdenum’s ability to withstand extreme temperatures without significant thermal expansion or softening makes it useful in applications involving intense heat, such as lighting filaments, aircraft parts, electrical contacts, industrial motors, and nuclear energy applications.
Molybdenum is also used in steel alloys to reduce brittleness, increase toughness, and enhance corrosion resistance.
In stainless steels it improves the strength and corrosion-resistance, a requirement for water distribution systems, food handling equipment, chemical processing equipment for home, hospital, and laboratory.
Alloy steels include the stronger and tougher steels for automotive parts, construction equipment, gas transmission pipes. Other major uses as an alloy include tool steels for bearings, dies, machining components; cast irons, for steel mill rolls, auto parts, crusher parts; superalloys for use in furnace parts, gas turbine parts, and chemical processing equipment.
