Description of Niobium Wire
Niobium wire, made from the chemical element niobium (Nb), is valued for its high melting point, corrosion resistance, and excellent superconducting properties. Typically produced via extrusion or drawing processes, niobium wire is refined to precise diameters to meet application requirements. It can be wound into coils for superconducting magnets or alloyed with other metals to improve mechanical and conductive properties, ensuring performance in high-demand settings like scientific research and aerospace.
