The C15 Laves phases with composition Nd(1-x)Pr(x)(Fe(0.35)Co(0.55)B(0.1))(2) (0 <= x <= 1) have been synthesized by arc melting and subsequent annealing. The Curie temperature T(c) and the saturation magnetizations M(s) at 5 and 295 K decrease with increasing Pr content. The linear anisotropic magnetostriction lambda(a) = lambda(parallel to)-lambda(perpendicular to) at room temperature for Nd(1-x)Pr(x)(Fe(0.35)Co(0.55)B(0.1))(2) alloys with 0 <= x <= 0.4 initially reaches a negative minimum, then increases and changes its sign with increasing magnetic field H, and the lambda(a) for the alloys with x >= 0.6 is positive and increases as magnetic field H increases.
