Niobium Wire
Description
Niobium (Nb) is a lustrous, light gray, ductile, metallic element that resembles tantalum chemically, platinum in color. Niobium wire is made of niobium bar through the following steps: i) rolling niobium bar to the right size, ii) acid pickling surface of niobium rods to remove oil and impurities, iii) cleaning with clear water, trimming both ends of the niobium rod, and iv) according to the actual needs, trimming and stretching for several times until get the right size of the niobium wire.
Alfa Chemistry supplies a wide range of niobium wire with competitive prices and unrivaled customer service. We can also customize various shapes of niobium products according to your requirements or drawings.
