The Science Behind C103
Niobium C103 is a refractory metal alloy composed of approximately 89% niobium, 10% hafnium, and 1% titanium. This precise formulation creates a material with extraordinary properties that make it indispensable in extreme environments.
- Extreme temperature resistance
- Excellent creep resistance
- High tensile strength
- Superior formability
- Low neutron absorption
- Oxidation resistance
- Corrosion resistance
- Good weldability
Refractory Metal Advantage
Refractory metals like niobium C103 are defined by their extremely high melting points (over 2000°C) and ability to maintain strength at elevated temperatures where most metals fail.

Manufacturing Process of Niobium C103 Wire
Producing Niobium C103 wire requires specialized processes to maintain material integrity while achieving precise dimensions.
1. Alloy Preparation
High-purity niobium, hafnium, and titanium are precisely measured and blended according to the C103 specification (Nb-10Hf-1Ti) to ensure exact chemical composition.
2. Vacuum Arc Melting
The alloy is melted in a high-vacuum environment to eliminate gas impurities and ensure homogeneous composition, creating a uniform ingot structure. Multiple melts ensure chemical uniformity.
3. Ingot Processing
The ingot is hot-worked through forging and rolling processes to reduce its cross-section and prepare it for wire drawing, while maintaining the material's grain structure.
4. Wire Drawing
The prepared stock undergoes multiple cold drawing passes through diamond dies, with intermediate annealing steps to relieve stress and maintain ductility, gradually reducing to the final wire diameter.
5. Final Annealing & Finishing
Final heat treatment optimizes mechanical properties. Surface finishing processes may include pickling or electropolishing to achieve the required surface quality.
6. Testing & Packaging
Each batch undergoes rigorous testing before being spooled or cut to length and packaged according to customer specifications.
