A casting roll of a two-roll continuous casting installation is to be able t o be exposed to a changing temperature stress and roll pressures when casting str ip made of non-ferrous metals, especially of aluminum or an aluminum alloy. For this purpose, its sleeve is made of an age-hardening copper alloy made of - as expressed in each case as weight % - 0.4 % through 2 % cobalt, which is partially exchangeable for nickel, 0.1 % through 0.5 % beryllium, optionally 0.03 % through. 0.5 % zirconium, 0.005 % through 0.1 % magnesium and possibly a maximum of 0.15 % of at least one element of the group including niobium, manganese, tantalum, vanadium, titanium, chromium, cerium and hafnium, the remainder being copper and inclusive of manufacturing- conditioned impurities and usual processing additives.
