Continuous casting uses a mold made of copper allow which includes from 0.01% to 0.15% boron, 0.01 to 0.2% magnesium, the remainder being copper as well as manufacture-dependent inpurities and working additives; in addition, at least one additive from the group is used at stated percentages: from 0 to 0.05% silicon, from 0 to 0.5% Ni, from 0 to 0.03% iron, from 0 to 0.03% titanium, from 0 to 0.2% zirconium, from 0 to 0.04% phosphorus, at a total content not exceeding 0.6%, all percentages by weight; the silicon content should be from 0.02% to 0.04%, and the nickel content should be from 0.1 to 0.5%. The mold is made in several working and annealing steps, the last step should be a cold working step with at least 10% deformation.
