Manufacturing Process
Raw Material → Vacuum melting (VIM/AOD) → Ingot casting
Hot Working → Forging/Rolling (850–1200°C) → Billets/Slabs
Cold Working → Drawing/Rolling → Intermediate annealing (650–900°C)
Finishing → Pickling (HNO3+HF) → Polishing/Coating
Quality Control → Spectrometry/NDT → Dimensional inspection
Applications
Electronics: Spark plug electrodes, lead frames, connectors.
Welding: Resistance welding tips, seam welding rollers.
Aerospace: Waveguides, thermocouple sheaths.
Energy: Heating elements, nuclear reactor components.
Key Advantages
Near-copper conductivity with better oxidation resistance.
Excellent weldability (TIG/MIG/Resistance).
Stable performance from cryogenic to 500°C.
