Pure Molybdenum AM Powders
Elmet Technologies is a global leader in pure molybdenum AM powder production, delivering premium-quality materials for laser-powder bed fusion additive manufacturing processes. We meticulously craft our molybdenum powder to deliver exceptional high-temperature strength, outstanding corrosion resistance, a low thermal expansion coefficient, and superior thermal conductivity. We ensure low oxygen content, excellent flowability, and high apparent and tap densities, making our molybdenum powder a versatile material trusted across numerous industries and applications.
Our pure molybdenum AM powder shares many characteristics with pure tungsten but excels with its significantly lower density—just half that of tungsten—making it an optimal choice for lightweight applications that demand uncompromising strength and durability. At Elmet, we ensure precision in every process, producing molybdenum and molybdenum alloy powders with tightly controlled particle size distributions, targeting a mean particle size range of 3-30 µm.
