Abstract (en)
Metal cord (100, 200, 300, 510, 520, 530) for reinforcing elastomer products comprising n metal filaments (105, 210) twisted together in a cord twisting direction, all the metal filaments (105, 210) have the same cord twisting pitch, wherein at least one metal filament (210) has a cross section which deviates from a round cross section, e.g. a flat, oval or rectangular cross-section. The metal cord (100, 200, 300, 510, 520, 530) has high rubber penetration, high strength and high fatigue resistance. Also, the use of the metal cord (100, 200, 300, 510, 520, 530) for reinforcing rubber product, e.g. a breaker layer of a tire, is disclosed.
