C-103 Niobium Alloy for High Performance Space Applications

Now available from Materion, C-103 niobium alloy is well-suited for rocket and jet propulsion applications including spacecraft and launch vehicles.

C-103 niobium alloy, formerly part of the H.C. Starck product line, is well-suited for rocket and jet propulsion applications utilized in spacecraft and launch vehicles. C-103 niobium alloy also has excellent resistance to high frequency vibrations at cryogenic temperatures, as occur in many satellite applications, because of its low ductile-to-brittle transition temperature.
