Molybdenum Properties

Molybdenum is a formidable choice for high-temperature applications, due to its high-temperature strength, high hardness, high melting point, high electrical and thermal conductivity, high corrosion resistance and relatively low coefficient of thermal expansion. Moybdenum is commonly called out for use in aerospace and defense projects involving missiles, propulsion units and engines, and in applications involving nuclear fuel processing — really any application requiring great strength at high temperatures.

Molybdenum can withstand many acids, including sulfuric, hydrochloric, hydrofluoric, and most organic acids, as well as many molten materials, such as metals, alloys, glasses, and compounds. In fact, molybdenum is often added to stainless steel to improve its corrosion resistance. It is corroded by alkalis in the presence of oxidants.
