Most Zirconium is used as an alloy, particularly in nuclear applications, where alloying improves corrosion resistance and mechanical performance. Pure Zirconium is also supplied when its inherent properties are required. The typical grades of Niobium are low oxygen zirconium (Grade R60700), unalloyed zirconium (Grade R60702), zirconium-tin (Grade R60704), zirconium-niobium (Grade R60705), and zirconium-niobium (Grade R60706)
