Unique Properties of Niobium Wire
Ductility and Forgeability
Niobium wire is highly ductile and forgeable, allowing it to be easily formed into a variety of shapes without compromising its strength.
High Melting Point
With a melting point of 2,468 degrees Celsius, niobium wire can withstand extreme temperatures, making it suitable for high-temperature applications.
Corrosion Resistance
Niobium wire is highly resistant to corrosion, making it ideal for use in environments where other metals may degrade over time.
Superconductivity
Nb metal wire exhibits superconducting properties at low temperatures, making it valuable in applications that require zero electrical resistance.
Low Thermal Expansion
Niobium wire has a low coefficient of thermal expansion, meaning it expands and contracts minimally with temperature changes, maintaining its shape and integrity.
Biocompatibility
Niobium is biocompatible, making it suitable for use in medical implants and devices where compatibility with the human body is critical.
Niobium is a chemical element with the symbol Nb and atomic number 41. It is a soft, grey, ductile transition metal. It has physical and chemical properties similar to the element tantalum, and the two are therefore difficult to distinguish.
Nb is used in various superconducting materials. These superconducting alloys, also containing titanium and tin, are widely used in the superconducting magnets of MRI scanners. Other applications of Nb include welding, nuclear industries, electronics, optics, numismatics, and jewelry. In the last two applications, the low toxicity and iridescence produced by anodization are highly desired properties.
