Lift Off with H.C. Starck’s C-103 Niobium Alloy

H.C. Starck’s C-103 niobium alloy with niobium-hafnium-titanium is well-suited for rocket and jet propulsion applications utilized in spacecraft and launch vehicles. A key advantage of the niobium alloy is its high strength at temperatures up to 2700 °F (1482 °C), particularly in high performance rocket nozzle applications. H.C. Starck’s 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.
