Application Fields
Nuclear Energy & Industry: Nuclear reactor control rod material (high neutron absorption, radiation resistance, corrosion resistance); Key components for nuclear submarines, nuclear fuel cladding.
Aerospace: High-temperature structural components, engine parts, thermal protection plates (high-temperature resistance, high strength); Locations requiring corrosion resistance and high strength like aero-engine combustion chambers and nozzles.
Semiconductors & Vacuum Coating: Vacuum evaporation targets, magnetron sputtering targets for manufacturing integrated circuits and optical thin films; High-purity Hafnium plates can be directly processed into target blanks, meeting the cleanliness requirements of microelectronic processes.
High-End Electronic Devices: High-power capacitors, high-temperature resistant electrodes, RF components (high melting point, low resistivity).
Special Alloys & Material R&D: Alloying with metals like Tantalum, Tungsten, Molybdenum to enhance high-temperature strength and oxidation resistance; Used as experimental material for researching new superalloy systems.
Product Advantages
Exceptional Thermal Stability: Melting point ≈ 2227°C, maintaining mechanical integrity in extreme high-temperature environments.
Excellent Mechanical Strength & Workability: High tensile strength, hardness, and sufficient toughness enable it to withstand heavy loads while allowing for hot/cold working (bending, stamping, rolling).
Superior Corrosion Resistance: Resistant to most acids and alkalis, dissolving only in hydrofluoric acid and aqua regia, suitable for harsh media including strong acids, alkalis, and seawater.
Nuclear Neutron Absorption: Large thermal neutron absorption cross-section (115 barn), making it an ideal material for nuclear control rods.
High Purity & Customization: Available in 99.95% - 99.99% purity, customizable in thickness, dimensions, and surface finish (bright, polished) to meet specific industry needs.
Mature Processing Technology: Proprietary multi-pass hot rolling + vacuum annealing process ensures fine grains, uniform structure, and reduced risk of oxidation and cracking.
Chemical Properties Overview
Chemical Inertness: Generally unreactive in dilute hydrochloric acid, dilute sulfuric acid, and strong alkalis; dissolves in hydrofluoric acid and aqua regia.
Alloying Behavior: Readily forms isomorphous alloys with Zirconium (Zr); can replace Zr in alloys to enhance high-temperature properties.
Neutron Absorption: Thermal neutron capture cross-section ~115 barn, significantly higher than Zirconium (0.18 barn), used in nuclear engineering to control neutron flux.
Mechanical Properties Overview
Tensile Strength: Pure Hf ≥ 380 MPa; common Hf-Ta-W alloys can reach 1030 MPa (Room Temperature).
Yield Strength: Alloy yield strength ~980 MPa (Room Temperature).
Elongation: Alloy elongation ~15% at room temperature; retains some plasticity (elongation ≈ 67%) at 1482°C.
Hardness: High hardness suitable for precision components; can undergo cold working (bending, stamping) without easy cracking.
Typical Processing & Quality Control
Material Preparation: Hafnium ingot heated to 1000 - 1200°C, held for 1 - 3 hours, then forged (forging ratio 3 - 5).
Hot Rolling: Forged slab undergoes multi-pass hot rolling at 700 - 900°C to form a hot-rolled plate.
Vacuum Annealing: The hot-rolled plate is cut, leveled, and vacuum annealed to relieve internal stress and refine the grain structure.
Finishing: Machining, degreasing, and pickling yield the final Hafnium plate, with surfaces available in bright or polished finishes.
