EN 2.4815 (G-NiCr15) Cast Nickel

EN 2.4815 cast nickel is a nickel alloy formulated for casting. Cited properties are appropriate for the as-fabricated (no temper or treatment) condition. 2.4815 is the EN numeric designation for this material. G-NiCr15 is the EN chemical designation.

It has a moderately low ductility among cast nickels. In addition, it has a moderately low base cost and a moderately low tensile strength.

The graph bars on the material properties cards below compare EN 2.4815 cast nickel to: cast nickels (top), all nickel alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
