Abstract (en)
[origin: EP3375898A1] A copper alloy material has a composition including: 0.3 mass% or more and less than 0.5 mass% of Cr; 0.01 mass% or more and 0.15 mass% or less of Zr; and a Cu balance including inevitable impurities, wherein an average of crystal grain sizes is in a range of 0.1 mm or more and 2.0 mm or less, and a standard deviation of the crystal grain sizes is 0.6 or less.
