ABSTRACT:
A casting metal mold made of a copper alloy consisting essentially of 0.01 to 3 wt % of zirconium, 0.03 to 5 wt % of titanium and, as required, 0.03 to 2 wt % of chromium and the balance substantially copper, the copper alloy having a structure in which precipitate phase consisting of compound of copper and at least one of zirconium, titanium and chromium exists, and having a Brinell hardness between H.sub.B 100 to H.sub.B 500 and an electric conductivity between 20 and 80% in terms of IACS. This metal mold suffers only small deformation during casting and, hence, less liable to cause run-out of the melt. The casting obtained by this metal mold, therefore, has no or only slight fins.
