High-Precision Niobium Machined Parts from Baoji Aulister Import and Export Co., Ltd.

Baoji Aulister Import and Export Co., Ltd. is a professional non-ferrous metal processing and export factory based in Baoji, China, the world-famous refractory metal industrial base. We integrate independent production, precision machining and global sales, covering core product lines including titanium, tantalum, niobium, molybdenum, nickel, metal sputtering targets and custom precision machined components. Among our star offerings, customized niobium machined parts stand out for outstanding material performance, strict dimensional tolerance control and full-spectrum custom service, serving industrial buyers across aerospace, medical, semiconductor, chemical engineering and superconducting technology worldwide.

Niobium (Nb) is a premium refractory metal with irreplaceable physical and chemical merits, making its precision components essential for extreme working environments. It features a melting point up to 2468°C, excellent ductility, ultra-low thermal expansion coefficient and superior corrosion resistance against most acids, alkalis and molten liquid metals. Unlike brittle tungsten or molybdenum, niobium can be processed into intricate thin-walled structures without cracking; its non-toxic, fully biocompatible property also qualifies it for long-term human implantation. At cryogenic temperatures, pure niobium and Nb-Ti alloys exhibit stable superconductivity, a core advantage for MRI equipment, particle accelerator magnets and quantum computing hardware.

As a local integrated niobium processor, we control the full production chain from raw niobium ingots to finished precision parts. Our factory deploys multi-axis CNC machining centers, diamond turning lathes, surface polishing equipment and full-set material testing labs. We supply pure niobium (Nb1, Nb2, purity ≥99.95%) and mainstream niobium alloys including Nb-1Zr, Nb-47Ti, Nb-7.5Ta, complying with international standards ASTM B393 and ASTM B654. Our product portfolio covers niobium flanges, vacuum cavity blocks, threaded fasteners, crucibles, evaporation boats, micro capillary tubes, medical implant blanks and complex multi-hole structural components. All parts support drawing-based OEM customization, with tight tolerances down to ±0.005mm and customizable surface finishes: matte as-annealed, mirror polishing, sandblasting or chemical passivation.

Our niobium machined components power multiple high-end industries. In aerospace, heat-resistant niobium structural parts are applied to rocket engine cooling channels and satellite ion thruster assemblies, maintaining dimensional stability under drastic temperature fluctuations. For medical manufacturing, biocompatible niobium screws, bone plates and dental base frames avoid tissue rejection and withstand repeated sterilization cycles. Semiconductor and vacuum clients choose our niobium vacuum fittings and gas delivery pipes for ultra-high purity production environments, free from metal ion contamination. Chemical factories adopt niobium reactors and valve bodies to resist severe corrosive media, drastically extending equipment service life. Meanwhile, research institutes rely on our superconducting niobium machined parts for NMR, accelerators and low-temperature lab devices.

Quality control runs through every procedure. We conduct raw material spectral analysis, dimensional coordinate detection, surface defect inspection and corrosion resistance testing, providing official Mill Test Certificates meeting EN 10204 3.1 standard. Flexible order rules cover small-batch prototype sampling and mass bulk production, with adjustable MOQ to support startup labs and large industrial manufacturers alike. Our international trade team delivers one-stop export solutions, including seaworthy anti-collision wooden case packaging, full customs documentation, and flexible FOB/CIF pricing terms for global shipping. We have stable client cooperation across Europe, North America, Southeast Asia and the Middle East, with 7×24 technical support to resolve drawing optimization, material selection and machining difficulty inquiries.
