Grade CZ100 (J02100) Cast Nickel
Grade CZ100 nickel is a nickel alloy formulated for casting. Cited properties are appropriate for the as-fabricated (no temper or treatment) condition. CZ100 is the ASTM designation for this material. J02100 is the UNS number.
It has the highest electrical conductivity among cast nickels. In addition, it has the lowest tensile strength and the highest thermal conductivity.
The graph bars on the material properties cards below compare grade CZ100 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.
