    Niobium Sheet

    Description:

    Material: RO4200-1, RO4210-2A
    Standard: ASTM B392-98
    Purity: Nb >99.9%, >99.95%

    Application:

    As a high temperatures and corrosive materials, niobium sheet and strip is commonly used in the industrial diamonds production, deep draw application and also chemical industrial with medical fields. Additionally niobium is used to make colored jewelry. We can provide bright surface finishing that is perfect for such applications which involve anodizing.
