Hafnium Metal Bars
🛠️ Hafnium Metal Bars (Hf) – High-Purity, Advanced Industrial Grade
Our Hafnium Metal Bars are high-purity metallic bars designed for advanced industrial, nuclear, aerospace, and microelectronic applications. Hafnium (Hf) is a rare, silvery-gray transition metal, naturally occurring in zirconium-containing ores and renowned for its high melting point, corrosion resistance, and exceptional neutron absorption capability.
Key Features & Benefits
- Exceptional Purity: Hf + Zr ≥ 99.8% ensures top-quality performance.
- Precision Dimensions: Max Ø 35 mm, length 100–150 mm, suitable for machining and alloying.
- Low Impurities: Zr ≤ 0.3%, ensuring optimal physical, chemical, and nuclear performance.
- Strict Quality Standards: Manufactured according to ASTM B737-10(15), Grade R3.
- Safe Transport: Vacuum-sealed, corrosion-resistant packaging maintains material integrity.
Applications
- Nuclear Industry: Control rods, reactor components, nuclear fuel cladding.
- Aerospace & Defense: Alloyed with titanium, tantalum, or nickel-based superalloys; turbine blades, rocket nozzles, spacecraft components.
- Microelectronics / Semiconductors: Precursor for hafnium oxide (HfO₂), high-k dielectrics in modern semiconductor fabrication.
- Metallurgy & Advanced Materials: Superalloys, wear-resistant coatings, corrosion-resistant components.
- Research & Development: Materials science, high-temperature engineering, chemical experiments.
