Molybdenum Alloys
Molybdenum is a silvery-white metal that is ductile and highly resistant to corrosion. It has one of the highest melting points of all pure elements — only the elements tantalum and tungsten have higher melting points. Molybdenum Alloys is also a micronutrient essential for life.
Molybdenum Alloys in Brief
High Temperature & Corrosion Resistant Alloys.
Molybdenum (Mo) is a refractory metallic element that readily forms hard, stable carbides and has the sixth-highest melting point of any element. Molybdenum is most commonly used as a high temperature, corrosion resistant metal alloy in steel, cast iron and super alloys for the marine industry, semiconductor industry and specialty machine shops.
Molybdenum enhances hardenability, strength, toughness, and resistance to wear and corrosion. This versatility makes Molybdenum a fixture in contemporary industrial technology, which increasingly requires materials that can withstand high stress, expanded temperature ranges and highly corrosive environments, all without significantly expanding or softening.
Molybdenum alloys are available in coil, sheet, bar, rod, plate flat stock and wire at XOT Metals. Take advantage of our competitive prices and reliability, along with our unique ability to recognize your specific needs and identify the most effective solution.
