Molybdenum
Elmet Technologies is a leading North American producer of pure molybdenum (Mo). We are unique in our ability to perform end-to-end manufacturing, starting with molybdenum oxide reduction to produce high-purity Mo metal powder. We then transform this powder using advanced powder metallurgy techniques – pressing, sintering, rolling, swaging, and drawing – to create fully dense flat and round mill products. Our comprehensive range of products includes rods, sheets, plates, foils, wires, and more, available for direct purchase or further enhancement through our world-class fabrication and machining services.
We precisely control material properties like ductility, tensile strength, hardness, and grain size through our comprehensive manufacturing process, tailoring each product to meet specific application needs. Elmet is committed to excellence, operating under ISO9001 and AS9100 certified quality management systems.

Molybdenum ALloys in high temperature ENVIRONMENTS
- MoLa: A composite blend of molybdenum and lanthanum oxide (La2O3), is valued for high-temperature applications. Its outstanding mechanical strength and thermal stability make it an exceptional choice for demanding environments.
- TZM: Offers increased strength at elevated temperatures compared to pure molybdenum. Additionally, TZM features a higher recrystallization temperature and enhanced resistance to creep.
- HCT: Ideal for applications requiring low-temperature ductility after high-temperature exposure. Perfect for heating elements, lamp supports, sintering trays, and electronic components. Recrystallized HCT molybdenum forms elongated grains, maintaining excellent ductility even at low temperatures.
