| Density | 8.57 g/cm3 |
| CAS Number | 7440-03-1 |
Niobium is a soft and ductile metal, which makes it a good material for tubes, pipes, and even capillary tubes. The purity of the niobium can be up to 99.95%. An estimated 90% of niobium mined was used in high-grade structural steel. The second largest application is superalloys. Niobium alloy superconductors and electronic components account for a small share of the world production. Various dimensions of the niobium tubing are available. Please contact us for more details.
Application: Niobium-Nb capillary tube has features of metallic luster, no color changed by hydrogenation and oxidation, no scratch, no deformation and etc. and it can be used to make special instruments, etc.
