Grade N12MV (J30012) Cast Nickel
Grade N12MV nickel is a nickel alloy formulated for casting. Cited properties are appropriate for the heat treated (HT) condition. N12MV is the ASTM designation for this material. J30012 is the UNS number.
It has a moderately low heat capacity among cast nickels. In addition, it has a moderately high embodied energy and a moderately high base cost.
The graph bars on the material properties cards below compare grade N12MV 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.
