Abstract: The invention relates to a nickel alloy derived from René 125, but with reduced levels of certain elements (Zr, B, P, S, Si and, to a lesser extent, Ti and Hf) in order to limit the appearance of cracks upon solidification in a moulding process. Specifically, 4.80%≦Al≦5.00%, 1.48%≦Hf≦1.52%, 2.28%≦Ti≦2.33%, 0.005%≦B≦0.01%, 1.77%≦Mo≦1.97%, and Zr≦0.007%. Other elements can have levels that match those of René 125.
