Applications of Niobium Wire:

1. Niobium wire is widely used for steel, ceramics, electronics, nuclear energy industries and superconductor technology.
2. For super condouctous ,metled cast ingots and alloying agents .

Niobium belongs to the group of refractory metals. Refractory metals are metals that have a higher melting point than platinum (1 772 °C). In refractory metals, the energy binding the individual atoms together is particularly high. Refractory metals have a high melting point coupled with a low vapor pressure, high modulus of elasticity and high thermal stability. Refractory metals are also characterized by a low coefficient of thermal expansion. Compared to other refractory metals, niobium has a relatively low density of only 8.6 g/cm3.

Our high-quality niobium wire is used in chemistry, electronics, aviation & aerospace, electric light source, reaction container, heat exchanger & sleeve materials. Niobium wire and alloyed niobium have a high melting point, corrosion resistance, good cold processing properties and other superb features.
