        For niobium sputtering target, we focus on to offer our customers with high purities ranging from 3N5 to 5N, fine and uniform grain size, elimination of strong texture banding, and early target life size stability.
        Our niobium sputtering targets' metallic impurities and gaseous impurities have been measured by known authorities around the world.
        Besides, we also offer program of recycling reclaimed scrap targets.
        niobium target is used as barrier metal for copper wiring device.
