Composition and Standard Grade: Nb-1Zr / Nb1Zr - Composition: Zr 0.8–1.2 wt%, Nb balance; minor impurities (C, O, N, H, Fe, Ta, etc.) Standard: ASTM B393 (Type 3 / Type 4) - Condition: Annealed (M-state): good ductility, easy to form, medium strength, Cold work hardened (Y-state): higher strength, greater hardness, slightly reduced toughness Plate Core Properties Density: ≈8.57–8.59 g/cm³ - Melting point: ≈2410℃ (extremely high melting point) - Strength: Tensile strength at room temperature: 195–330 MPa (annealed) - Strength of ≈150 MPa at 800℃ (much stronger than pure Nb) - Corrosion resistance: resistant to strong acids, strong alkalis, and corrosion by liquid metals (sodium, lithium) - Low thermal neutron cross-section: key advantage in nuclear industry Processability: can be rolled, stamped, welded, cut, with good formability Typical Specifications (Plate) Thickness: 0.05–20 mm Width: 100–1000 mm Length: 500–3000 mm Surface: Pickled / Bright / Brushed / Polished
Main Applications (Plate Scenario) 1. Aerospace - High-temperature heat shields, combustion chamber components, rocket nozzle liners 2. Nuclear Industry - Reactor structural components, heat shields, cladding, neutron absorbers 3. Chemical Corrosion-resistant reactor liners, heat exchanger plates, corrosion-resistant containers 4. Electric Light Sources / Electronics High-pressure sodium lamps, special electronic devices, sputtering targets 5. Medical Orthopedic / Dental Implant Substrates (good biocompatibility) Compared to Pure Nb Plate Nb1%Zr Plate: higher strength, more stable at high temperatures, better creep resistance, slightly higher price Pure Nb Plate: softer, better ductility, lower price, prone to softening at high temperatures
