Grade M35-2 (J04020) Cast Nickel

Grade M35-2 nickel is a nickel alloy formulated for casting. Cited properties are appropriate for the as-fabricated (no temper or treatment) condition. M35-2 is the ASTM designation for this material. J04020 is the UNS number.

It has a moderately low melting temperature among the cast nickels in the database.

The graph bars on the material properties cards below compare grade M35-2 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.
