Summary: | Provided is a copper alloy containing 18% by mass to 30% by mass of Zn, 1% by mass to 1.5% by mass of Ni, 0.2% by mass to 1% by mass of Sn, and 0.003% by mass to 0.06% by mass of P, the remainder including Cu and unavoidable impurities. Relationships of 17<=f1=[Zn]+5x[Sn]-2x[Ni]<=30, 14<=f2=[Zn]-0.5x[Sn]-3x[Ni]<=26, 8<=f3={f1x(32-f1)} 1/2x[Ni]<=23, 1.3<=[Ni]+[Sn]<=2.4, 1.5<=[Ni]/[Sn]<=5.5, and 20<=[Ni]/[P]<=400 are satisfied. The copper alloy has a metallographic structure of an a single phase.
Alliage de cuivre contenant 18 à 30 % en masse de Zn, de 1 à 1,5 % en masse de Ni, de 0,2 à 1 % en masse de Sn, et de 0,003 à 0,06 % en masse de P, le reste étant constitué par Cu et par des impuretés inévitables, les relations représentées par les formules mentionnées ci-dessous étant remplies : 17 = f1 = [Zn]+5×[Sn]-2×[Ni] = 30, 14 = f2 = [Zn]-0.5×[Sn]-3×[Ni] = 26, 8 = f3 = f1×(32-f1)}1/2×[Ni] = 23, 1.3 = [Ni]+[Sn] = 2.4 et 1.5 = [Ni]/[Sn] = 5.5 et 20 = [Ni]/[P] = 400. L'alliage de cuivre présente une structure métallique à phase unique a. |
