Deep Processing Of Niobium Metal

Niobium metal boasts a high melting point, excellent plasticity, stable chemical properties, and strong corrosion resistance. It is resistant to volatilization, absorption, and outgassing in high-temperature vacuum environments. As a result, it is commonly used as a rare metal component in high-end, high-temperature, corrosion-resistant, and vacuum industries.
The commonly used materials are high-purity niobium (Nb99.9%, Nb99.95%, Nb99.99%), with no alloy additions. They are soft in texture, have good ductility, and are easy to bend, weld, and process precisely. Our products cover basic profiles such as niobium plates, rods, tubes, wires, tapes, and foils, as well as precision-processed items like niobium crucibles, boats, trays, insulation cylinders, flanges, plugs, nozzles, electrode assemblies, non-standard shaped parts, and welded structural components.
The material boasts a melting point of up to 2468℃, demonstrating excellent high-temperature resistance. It exhibits good chemical stability, resisting corrosion from acids, alkalis, and molten salts, and does not react with aqua regia at room temperature. Its vacuum high-temperature outgassing is extremely low, making it suitable for various high-temperature vacuum equipment. Additionally, it possesses excellent plasticity, facilitating easy processing and welding. It is non-magnetic and possesses good thermal and electrical conductivity.
It is widely used in various fields such as vacuum heat treatment furnace components, high-temperature experimental vessels, chemical corrosion-resistant parts, optoelectronic semiconductor components, cemented carbide sintering fixtures, aerospace high-temperature structural components, and rare metal melting crucibles.
After undergoing processes such as forging, rolling, and vacuum annealing, niobium materials exhibit uniform and stable internal structures, refined grains, and optimized mechanical properties and surface conditions. The processing strictly controls dimensional tolerances and surface roughness, ensuring the absence of oxidation interlayers, cracks, and impurity defects, and excellent welding sealing. Under long-term high-temperature conditions, it is resistant to deformation, embrittlement, and volatilization loss. It can adapt to harsh vacuum environments, corrosive environments with molten media, and high-temperature inert atmosphere conditions, and its service life is significantly longer than that of ordinary high-temperature resistant metal materials.
We can customize various non-standard structural parts, irregular parts, and precision machined parts according to customer drawings. We support customization of dimensions, surface polishing, weld treatment, and delivery under special conditions.
