Niobium Sheet Applications

As a high-temperatures and corrosive material, niobium foil and strip are commonly used in industrial diamond production, deep draw application, chemical industrial, and medical fields. Additionally, niobium is used to make colored jewelry. We can provide bright surface finishing that is perfect for such applications that involve anodizing.

Surface Treatment of Niobium Sheet

Surface can be supplied in a shiny, matte, satin, or as-rolled condition, depends upon thickness and width parameters.

Heat Treatment of Niobium Sheet

Niobium flat products are rolled and annealed to provide the optimum condition for the desired end-use.
