What are Niobium C-103 / C103 Alloy Fasteners?
Niobium C-103 / C103 Alloy is a high-performance refractory alloy primarily consisting of niobium with controlled additions of hafnium and titanium. This alloy was originally developed for aerospace propulsion systems because of its outstanding strength-to-weight ratio and its ability to retain mechanical properties at extremely high temperatures.
Unlike conventional alloy steels, C-103 alloy offers:
- Excellent high-temperature strength
- Low density compared to nickel superalloys
- Superior thermal stability
- Excellent weldability and fabrication
- Good ductility
- Outstanding performance in vacuum environments
- Resistance to thermal fatigue
These properties make UNS R04295 Fasteners an ideal solution for critical assemblies exposed to extreme thermal cycling.
