Niobium Wire

Niobium Wire

Niobium wire is a preferred choice for jewelry making due to its hardness and corrosion resistance. By adding zirconium in niobium wire, the hardness and antioxidant properties can be greatly improved. Its diameter can be ranged from 0.4 mm to 1.5 mm or from 3.0 mm to 6.0 mm. Niobium wire can be offered by hot rolled, cold drawn or annealed process.

Niobium wire is often applied in the industry of chemical engineering, synthetic diamonds, superconductors, fiber optic or architectural glass, thin-film, reactors and high temperature vacuum furnaces and sodium vapor lamps.
