With the rapid advancement of high-end manufacturing, aerospace, chemical anti-corrosion and medical biomaterial industries, the global demand for refractory rare metals keeps growing. High-purity niobium plate has become an irreplaceable key raw material for many high-tech projects for its comprehensive outstanding properties. Niobium is a typical refractory rare metal with a melting point of 2468℃. It features high-temperature resistance, excellent corrosion resistance, good ductility and superconducting performance. After rolling, annealing and finishing, niobium plate delivers smooth surface, compact internal structure and tight dimensional tolerance to meet strict industrial requirements.
In chemical industry, niobium plate resists strong acid and alkali, widely applied for reactor liners and heat exchanger components. In aerospace field, it is adopted for engine hot-end parts and propulsion system assemblies thanks to high temperature resistance and low density. Benefiting from great biocompatibility, niobium plate serves as raw material for medical implants. For semiconductor and superconducting sectors, high-purity niobium plate works as blanks for sputtering targets and superconducting components. Custom sizes are available, including variable thickness, length and width, with typical purity ≥99.95% / 99.99%, complying with ASTM standards.
Q&A
Q1: How to tell niobium plate from tantalum plate?
A: They look similar visually. Niobium has much lower density, so niobium plate weighs less in the same dimension. Material certificate or spectrum test is recommended for accurate identification.
Q2: Can niobium plate be bent and welded?
A: Annealed niobium plate has good ductility for bending, cutting, welding and punching. Hard-state niobium is brittle, annealing treatment is suggested before processing.
Q3: What is the temperature resistance of niobium plate?
A: Melting point of niobium is 2468℃. It will oxidize rapidly under atmospheric high temperature. Long-term service temperature reaches 1000-1400℃ under vacuum or inert gas, while below 400℃ in air environment.
