Abstract (en)
[origin: EP3375897A1] A copper alloy material has a composition including: 0.1 mass% or more and 1.5 mass% or less of Cr; 0.05 mass% or more and 0.25 mass% or less of Zr; 0.005 mass% or more and 0.10 mass% or less of P; and a Cu balance including inevitable impurities. The copper alloy material includes a Cr-Zr-P compound containing Cr, Zr and P and an area ratio of the Cr-Zr-P compound is in a range of 0.5 % or more and 5.0 % or less in a structure observation, and the Cr-Zr-P compound is in a form of a needle shape or a granular shape and a length a longest side of the needle shape or the granular shape is 100µm or less.
