A brass material and a process for the preparation thereof, which comprises an alloy of 61 to 65% by weight of copper with the remainder being zinc; the material evidencing a structure in which the recrystallized phases alpha and beta 1 are present in a discrete fine mixture having grain sizes of less than 5 mu m. The component of the beta 1 phase comprises at least 10% of the structure and is arranged in the form of discrete particles in the grain boundaries of the alpha phase.
