A method of manufacturing a nozzle (26) for a fuel injector for internal combustion engines, comprising the steps of: - forming a multilayer bar (10) elongated in a longitudinal direction (A), having an inner core (12) of wear resistant material and an outer annular layer (14) of a corrosion resistant material which surrounds the inner core (12); - cutting the multilayer bar (10) in directions orthogonal to said longitudinal direction (A) to form a cylindrical blank (16) with planar front surfaces (18); - fixing a tip (20) of corrosion resistant material on one of said front surfaces (18) of said blank (16); and - shaping the blank (16) with the tip (20) fixed thereto into a finished nozzle (26).
