Zr Foil

1. Basic characteristics: physical background beyond conventional metals

    Zirconium (Zr) not only has an extremely high melting point (about 1852 °C), but its most unique charm lies in the self-healing oxide film on the surface. This dense ZrO2 film can reorganize instantly after encountering scratches, ensuring the integrity of the material under extreme fluid shocks.

    Low thermal neutron absorption: Zirconium has an extremely low absorption rate of thermal neutrons, making it an irreplaceable "transparent material" for the nuclear energy industry.

    Extreme acid resistance: In most organic acids, inorganic acids (such as hydrochloric acid, nitric acid) and strong bases, zirconium foil is even better than titanium alloy and tantalum material in corrosion resistance.

2. Chemical composition and technical indicators (Typical Values)

    We strictly screen raw materials to ensure that the impurity content is compressed to PPM level to ensure the consistency of mechanical properties of materials.

    R60702 Zr702: 99.2%Zr + Hf(4.5(Max), Fe+Cr 0.2(max)-- Zr+Hf+Fe+Cr

    R60704 Zr704: 97.5%Zr+Hf(4.5Max)+Tin1.0-2.0+Fe+Cr0.2-0.4--Zr+Hf+Tin+Fe+Cr

    R60705 Zr705:95.5%Zr+Hf(4.55Max)+ Fe+Cr0.2max+Nb2.0-3.0-- Zr+Hf+Fe+Cr+Nb

3. Lean process: from dense ingot to micron foil

    Our zirconium foil is not a simple calendered product, but a precision-manufactured crystallization:

    Vacuum Electron Beam Melting (EBM): Ensure the purity of zirconium ingots and eliminate gas impurities.

    Multi-pass cold rolling technology: Through the precision cold rolling mill, the thickness is precisely controlled at the micron level, while ensuring the isotropy of transverse and longitudinal properties.

    Online vacuum annealing: Eliminate the internal stress generated by cold processing, endow the zirconium foil with excellent flexibility and ductility, and ensure that brittle cracking does not occur during subsequent stamping.

4. Product specifications and basic information parameters

    Thickness (Thickness): 0.01 mm-0.1 mm (the thinnest can be customized to 0.001 mm)

    Width (Width): 5.0 mm-300mm

    Length: Continuous coil or sliced on demand

    Hardness state: annealed state (HV < 150) or work-hardened state (customized as required)

    Implementing standard: ASTM B551/ASME SB551 (industry standard); For nuclear energy applications, special nuclear-level specifications.

5. Finish: Mirror-grade gloss, flawless quality

    For the needs of vacuum deposition and semiconductor experiments, we provide a variety of surface states:

    Bright Finished: Mirror texture, extremely low bleed rate, suitable for ultra-high vacuum.

    Matte Finished: Surface force that facilitates specific fit processes.

    Ultrasonic cleaning: 100% removal of surface rolling oil and metal debris, ensure Ready-to-use (Ready-to-use).

6. Core advantage: Why do senior engineers choose our zirconium foil?

    Ultra-high purity stability: Especially for Low-Hafnium requirements, we control the hafnium (Hf) content below 0.01% to ensure neutron economy.

    Tolerance accuracy: Laser online thickness measurement is adopted, and the thickness tolerance is controlled within ± 5%, far exceeding the industry standard.

    Edge flatness: Using precision longitudinal shearing technology, there are no burrs and cracks on the edges, which greatly reduces the risk of failure in high-pressure sealing applications.

7. Application Areas: Core Materials to Drive the Future

    Nuclear power generation: Cladding, diaphragm and experimental materials for research reactors as internal components of nuclear reactors.

    Chemical anti-corrosion: Manufacturing fine chemical reactor lining, valve diaphragm and strong acid corrosion resistance compensator.

    Vacuum coating and semiconductors: as substrates for sputtering targets or for making special electron tube assemblies.

    Biomedical: Using its excellent bio-compatibility, it is used to manufacture special experimental membranes for medical implants.
