The article is devoted to the analysis of the quality of crystallographic texture in thin tapes made of a number of Cu–40%Ni–Me (Ме=Nb, Мо, W) ternary alloys, which have the prospect of being used as epitaxial substrates. The modes of recrystallization annealing are optimized, which allow to obtain a perfect cubic texture with a grain fraction {001}<100> of more than 96% in the belts of the studied alloys with a thickness of about 100 m. The proposed alloys are paramagnetic at the operating
