Abstract
A method for manufacturing casting molds, in particular continuous casting molds which are used with an electromagnetic rabbling mechanism in the continuous casting of steel, is provided. The method comprises selecting a specified age-hardenable copper alloy to have a Ni content from 0.1 to 2.0% which allows the electrical conductivity of the copper alloy to be adjusted from 80 to 35 IACS. The method further comprises melting, casting, hot-rolling, solution heat treating and rapidly cooling the copper alloy, followed by age-hardening, wherein the mold has a tensile strength of at least 430 N/mm , is highly thermally conductive and exhibits low magnetic field damping. A method of using an age-hardenable copper alloy is also provided.
