Description Of Custom Niobium Beads
Custom Niobium Beads are high-purity niobium metal beads manufactured from high-purity niobium (≥99.9%) through vacuum melting, forging, and precision processing. Niobium is a silver-grey refractory metal with a melting point of 2477°C, excellent corrosion resistance, and superior superconducting properties. These beads are available in custom sizes and weights to suit specific application requirements.
Niobium offers a unique combination of properties that make it ideal for demanding applications. With a melting point of 2477°C (the fourth-highest among all elements, after tungsten, tantalum, and rhenium), niobium beads can withstand extreme temperatures. The material also offers excellent corrosion resistance to acids, alkalis, and most molten metals, and it does not react with reactive metals like titanium, zirconium, and hafnium.
Custom niobium beads are widely used in evaporation coating (PVD) as an evaporation source, as alloy additives for titanium alloys and superalloys, in superconducting materials, and in laboratory research. They can be supplied in bright, pickled, or polished surface conditions, with custom sizes and weights available upon request.
