High Strength Material for Extreme Temperatures - Niobium C-103 Alloy

The niobium C-103 alloy with niobium-hafnium-titanium (Nb-10Hf-1Ti) from H.C. Starck Solutions meets challenging applications that require high strength materials to handle extreme temperatures. H.C. Starck Soutions’ niobium alloy can work at temperatures up to 2700 °F (1482 °C), mostly in high-performance rocket nozzle applications for space exploration. The niobium alloy can resist high-frequency vibrations at cryogenic temperatures, which occur in a number of satellite applications.
