ABSTRACT:
A copper-based alloy essentially includes 5.0 to 10.0 wt % of Zn, 2.8 to 5.0 wt % of Sn, 0.4 to 3.0 wt % of Bi, 0<Se≦0.35 wt %, 0<P≦0.5, one of 0<Sb≦2.2 wt % and 0<Ni≦4.8 wt %, and a balance of Cu and unavoidable impurities. It may essentially includes 5.0 to 10.0 wt % of Zn, 2.8 to 5.0 wt % of Sn, 0.4 to 3.0 wt % of Bi, 0≦Se≦0.35 wt %, 0<P<0.5 wt %, one of 0<Sb≦2.2 wt % and 0<Ni≦4.8 wt %, 1.20 to 4.90 Vol. % of at least one selected from the group consisting of a non-solid solution substance secured with Bi and a non-solid solution secured with Bi and Se, and a balance of Cu and unavoidable impurities.
