Niobium Sheet has a high melting point and high thermal stability. Niobium has a high melting point (about 2468 degrees Celsius) and excellent thermal stability, enabling it to work stably in high temperature environments for long periods of time. Pure Niobium Plate has excellent mechanical strength and toughness, can withstand large stress and deformation and is not easy to break.
Nb Sheet is a good conductor with low resistivity and is widely used in electronic devices and superconductors. Pure Nb Plate has good corrosion resistance to many chemicals and can maintain stability in corrosive environments such as acids and alkalis.
Nb Sheet has a low oxidation rate, so it is relatively stable in the atmosphere and does not react easily with oxygen.

Niobium Sheets and Plates are Premium Material Solutions for Advanced Technological Applications.
High-purity niobium sheets and plates (99.95%-99.99%) serve as fundamental components across cutting-edge industries due to their unique combination of electrical conductivity, thermal stability, and corrosion resistance. In electronics manufacturing, niobium sheets are essential for producing high-performance capacitors featuring low equivalent series resistance (ESR) and superior values, particularly valuable in high-frequency applications. These Nb sheets also function as ideal substrates for thin-film circuits and sputtering targets in semiconductor fabrication, with optimized electron migration resistance achieved through specialized processing to maintain residual resistivity ratio (RRR) values exceeding 300.
The superconducting applications of niobium plates are particularly noteworthy in advanced scientific equipment. High-grade niobium sheet forms critical components in SRF (superconducting radio frequency) cavities for particle accelerators, MRI magnet shielding systems leveraging the Meissner effect, and fusion reactor installations requiring materials with high critical temperature (Tc) performance. Our β-phase stabilized niobium plates undergo specialized treatment to prevent phase transformation during cryogenic operation, ensuring consistent performance in extreme environments.
Aerospace and defense applications benefit tremendously from niobium's exceptional properties, with plates being utilized in rocket engine combustion chambers capable of withstanding temperatures approaching niobium's 2468°C melting point. The material's radiation shielding capabilities make it invaluable for missile guidance systems and satellite components, available in standard grades ASTM R04200 and R04210 with complete material traceability.
For chemical processing applications, niobium demonstrates outstanding corrosion resistance with less than 0.1mm/year erosion rates in aggressive media including hydrochloric and sulfuric acids. This makes niobium sheets ideal for reactor vessel construction, electroplating anodes, and catalyst support grids in petrochemical operations. The Nb plate's stability in ultra-high vacuum conditions further expands its utility in specialized industrial processes.
In medical technology, niobium's biocompatibility (ASTM F2066 compliant) and MRI compatibility make it perfect for surgical implants and instruments. Medical-grade niobium sheets meet ISO 13485 certification requirements and are available with full biocompatibility documentation for dental membranes and orthopedic applications.
Available in thicknesses from 0.1mm foil to 50mm heavy plate, niobium products come with multiple surface finish options (mirror, matte, or etched) and full compliance with ASTM B393 and AMS 7852 standards. Special processing including electron beam welding (EBW) and precision rolling ensures optimal performance for superconducting, aerospace, and medical applications. With capabilities for custom sizing and specialized alloys (including Nb-Zr compositions), we provide tailored solutions for the most demanding technical requirements across industries ranging from quantum computing to next-generation space systems.
For technical specifications or application consultation, our materials engineering team provides comprehensive support to help select the optimal niobium plate solution for your specific requirements, whether for large-scale industrial deployment or precision research applications.
