Abstract
An Ni—Cu alloy having excellent surface properties consists, in mass %, C: 0.01 to 0.20%, Si: 0.01 to 0.5%, Mn: 0.01 to 2%, P: not greater than 0.03%, Cu: 28 to 40%, Cr: 0.01 to 1%, Fe: 0.3 to 3%, Al: 0.01 to 0.5%, Ti: 0.01 to 0.40%, N: not greater than 0.010%, Mg: 0.005 to 0.04%, Ca: 0.0005 to 0.04%, O: 0.0003 to 0.005%, S: 0.0001 to 0.002%, Ni and inevitable impurities as a remainder, and mass concentrations of Ti, N and C satisfy the following formula. [ % Ti ] × ( [ % N ] + 1 / 100 × [ % C ] ) < 0.0003
