Answer
Correct Answer: A higher
Explanation
ConceptNimonic grades are typically very high in Ni (often ~70–80% for classic grades like Nimonic 75), whereas common Inconel grades span ~50–72% Ni depending on type (e.g., 718 ~ 50–55%, 625 ~ ~60%, 600 ~ ~72%). Hence, in general wording, Nimonic contains a higher percentage of nickel than Inconel.
