Disclosed is a nickel-chromium alloy for the production of castings comprising 0.26-0.8% carbon, up to 1.0% silicon, up to 0.2% manganese, 15-40% chromium, 0.5-13% iron, 1.5-7% aluminium, up to 2.5% niobium, up to 1.5% titanium, 0.01-0.4% zirconium, up to 0.06% nitrogen, up to 12% cobalt, up to 5% molybdenum, up to 6% tungsten, 0.019 to 0.089% yttrium, and the remainder nickel. The nickel-chromium alloy is highly carbonation-resistant and oxidation-resistant and highly thermostable, particularly resistant to creeping, in a carbonating and oxidising atmosphere even at temperatures exceeding 1130 DEG C.
