What are the approximate percentages in the Zirconium Niobium Alloy Surface Transformation composition?

Explanation:
In zirconium-niobium alloys used for surface transformations, the classic designation is Zr-2.5Nb, meaning about 2.5% niobium by weight and the rest zirconium. So the approximate composition is 97.5% zirconium and 2.5% niobium. This specific Nb content is chosen to improve properties like strength and corrosion resistance without shifting the material away from zirconium’s favorable behavior. The other options imply Nb contents that don’t match this well-known alloy designation, so they don’t fit the standard Zr-2.5Nb composition.
