H.C. Starck’s niobium C-103 alloy with niobium-hafnium-titanium (Nb-10Hf-1Ti) meets demanding applications that require high strength materials to handle extreme temperatures. Our niobium alloy, performs at temperatures up to 2700°F (1482°C), particularly in high performance rocket nozzle applications for space exploration. The niobium alloy resists high frequency vibrations at cryogenic temperatures, which occurs in many satellite applications.
