Hafnium rod and bar, ASTM B737, high-purity material for nuclear and high-performance uses

Hafnium Rod-Bar

Key Advantages

Nuclear-grade purity: Hf + Zr > 99.98%, Zr < 1% for stable neutron absorption and high-purity performance in critical systems.
Flexible dimensions & shapes: Diameter 5–100 mm; round, square, hexagonal and custom profiles; cut-to-size for fast integration.
Controlled properties: Multiple conditions — cold rolled (Y), hot rolled (R), annealed (M), quenched (C) — to balance strength and ductility.
Certified quality system: Produced under ISO 9001 & AS9100 with compatibility to ASTM B737, ASME, DIN, NACE, SAE expectations.

Primary Applications

Nuclear energy: Control rods, absorber elements and safety components requiring reliable neutron capture and documented compliance.
Industrial & metallurgical: Getters and scavengers for oxygen/nitrogen in lamps and high-performance melting processes.
Aerospace & medical: High-temperature and precision components operating in aggressive or mission-critical environments.

Testing (Typical)

Visual inspection for surface quality (no cracks, laps or inclusions)
Ultrasonic flaw detection for internal integrity
Chemical composition analysis (Hf/Zr and impurities)
Mechanical testing as per project/standard requirements

Send your specifications (grade, size, quantity) — quotation and lead time within 12 hours. Trial orders with flexible MOQ are supported for evaluation and qualification. All materials are supplied with EN 10204 3.1 MTC and full inspection documentation for export compliance.
