Abstract (en)
[origin: US2020215604A1] A casting mold material used when casting a metal material includes, as a composition: Cr within a range of 0.3 mass % or more and 0.7 mass % or less; Zr within a range of 0.025 mass % or more and 0.15 mass % or less; Sn within a range of 0.005 mass % or more and 0.04 mass % or less; P within a range of 0.005 mass % or more and 0.03 mass % or less; and a balance consisting of Cu and inevitable impurities, in which a Zr content [Zr] (mass %) and a P content [P] (mass %) have a relationship of [Zr]/[P]≥5, and a Sn content [Sn] (mass %) and a P content [P] (mass %) have a relationship of [Sn]/[P]≤5.
