More Info

Niobium Rod (Niobium Bar) is worked from ingot to final diameter, forging, rolling, swaging, and drawing are used singularly or in combination to reach the desired size. We place the emphasis on absolute precision during the production of our niobium rod, TNTI insists on particularly low tolerances in terms of both diameter and roundness and guarantee rod of exceptional straightness.
