Tungsten Additive Manufacturing Powder
Elmet Technologies is the only US-owned, fully integrated manufacturer of tungsten additive manufacturing powder. We specialize in producing powders designed specifically for laser powder bed fusion (L-PBF) additive manufacturing processes. Our tungsten powders are known for their low oxygen content, superior flowability, and high apparent and tap densities. With tungsten being the element with the highest melting point, it is an ideal material for challenging applications in industries like aerospace and defense.
Additive manufacturing with tungsten offers numerous benefits, including the ability to produce intricate geometries, combine multiple components into one, customize designs, accelerate production, and reduce material waste. As specialists in powder metallurgy, we develop custom powder formulations tailored to meet our customers’ unique requirements. Our fully integrated production process enables precise control over material properties such as hardness, ductility, tensile strength, and grain size, ensuring alignment with specific application needs. This approach also streamlines production by consolidating parts and reducing the need for multiple components.
