C103 Additive Manufacturing Powder
Elmet Technologies proudly offers C103 additive manufacturing powder, meticulously designed for laser-powder bed fusion (L-PBF) processes. Engineered for high performance, this powder boasts low oxygen content, excellent flowability, and superior apparent and tap densities. These features make it an ideal solution for demanding applications in rocket and jet propulsion systems, such as spacecraft and launch vehicles.

One of the standout advantages of C103 AM powder is its exceptional strength, remaining highly effective at extreme temperatures of up to 2700°F (1482°C). Additionally, this advanced material exhibits remarkable resistance to high-frequency vibrations, even under cryogenic conditions. Its low ductile-to-brittle transition temperature further enhances its reliability, making it a top choice for critical satellite applications.
