Abstract
The copper alloy of the present invention contains 5% by mass to 25% by mass of Ni, 5% by mass to 10% by mass of Sn, 0.005% by mass to 0.5% by mass of element A (element A being at least one selected from the group consisting of Nb, Zr and Ti), and 0.005% by mass or more of carbon. In the copper alloy, the mole ratio of the carbon to the element A is 10.0 or less. The copper alloy may further contain 0.01% by mass to 1% by mass of Mn. In this copper alloy, the element A may be present as carbide.
