Overview: What is Spherical Niobium (Nb) Powder?

Niobium (Nb) is a ductile, corrosion-resistant metal with a relatively high melting point of 2,468°C (4,474°F). Its key properties include superconductivity, strength at high temperatures, och utmärkt korrosionsbeständighet, especially when exposed to chemicals.

Spherical niobium powder is niobium processed into a near-perfect spherical shape, providing better flytbarhet och Packningstäthet than irregularly shaped powders. This makes it highly suitable for 3D-utskrifter, pulvermetallurgi, and other advanced manufacturing techniques where consistent powder flow is crucial for part quality.

Key Properties and Characteristics of Spherical Niobium (Nb) Powder

Niobium is prized for its superconducting properties, making it an essential material in technologies such as MRI machines, particle accelerators, och quantum computing. Additionally, niobium is widely used in flyg- och rymdindustrin och kemisk bearbetning på grund av dess high temperature stability och korrosionsbeständighet.
