A nickel-base superalloy, in particular for the production of single-crystal components, consisting essentially of 6.0-6.8 % Cr, 8.0-10.0 % Co, 0.5-0.7 % Mo, 6.2-6.6 % W, 2.7-3.2 % Re, 5.4-5.8 % Al, 0.5-0.9 % Ti, 7.2-7.8 % Ta, 0.15-0.3 % Hf and 0.0.2-0.04 % C (all by weight) and 40-100 ppm B, the remainder being made up of nickel and impurities. The ratio (Ta + 1.5 Hf + 0.5 Mo - 0.5 Ti)/(W + 1.2 Re) >/= 0.7 |
