EN 1.4869 (GX50NiCrCoW35-25-15-5) Casting Alloy

EN 1.4869 casting alloy is a nickel alloy formulated for casting. Cited properties are appropriate for the as-fabricated (no temper or treatment) condition. 1.4869 is the EN numeric designation for this material. GX50NiCrCoW35-25-15-5 is the EN chemical designation.

The graph bars on the material properties cards below compare EN 1.4869 casting alloy 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.
