Columbium (Niobium) Alloy Foil, Sheet, Strip and Plate, 10W - 2.5Zr, Recrystallized
This specification covers a columbium (niobium) alloy in the form of foil, sheet, strip, or plate. This material has been used typically for parts requiring exposure at ultra high-temperatures, but usage is not limited to such applications. Applications in oxidizing atmospheres necessitate a protective coating.
