Niobium Sheet & Plate

Admat supplies niobium sheets and plates in a wide range of thicknesses and widths. We can offer flat rolled material cut to specific lengths or we can supply coiled sheet or strip shipped on cores. Although our products are typically produced to meet ASTM specifications, other specifications are available upon request.

Niobium sheet and strip is commonly used in the production process of industrial diamonds. This manufacturing process includes high temperatures and corrosive materials. Niobium is well suited for such environments. Admat produces thicknesses from .003″ to .015″ with mechanical properties ideal for deep draw applications.

Additionally niobium is used to make colored jewelery. Admat can provide bright surface finishing that is perfect for such applications which involve anodizing.
