C-103 Spherical Powder is a high-performance refractory metal alloy powder composed primarily of niobium (Nb), hafnium (Hf), and titanium (Ti). Originally developed for extreme-temperature aerospace and propulsion systems, C-103 alloy is renowned for its exceptional high-temperature strength, oxidation resistance, weldability, and thermal stability. The spherical powder form is specifically engineered for additive manufacturing, powder metallurgy, thermal spray, and advanced materials research applications.
Produced through advanced gas atomization processes, C-103 spherical powder features excellent flowability, high packing density, controlled particle size distribution, and low contamination levels. These characteristics make it ideal for laser powder bed fusion (LPBF), selective laser melting (SLM), directed energy deposition (DED), electron beam additive manufacturing (EBAM), and other advanced manufacturing technologies.
C-103 remains one of the most widely used niobium-based refractory alloys in aerospace propulsion systems, rocket engine components, satellite systems, and high-temperature engineering applications where lightweight materials must withstand extreme operating conditions.
