Abstract
A steel cord for reinforcing automobile tires is composed by intertwisting at least one material wire having small spiral-like curls and 1 to 5 straight material wires. This restricts the ratio of fracture elongation of the two kinds of material wires as well as the elongation percent of the cord at 5 kg loading and improves the stability of twist, the fatigue resistance, the penetrability of a rubber compound and the handling workability.
