The present invention discloses a high-strength tin-plated bronze tire bead steel wire, which comprises a steel wire base body. The surface of the steel wire base body is provided with at least two plating layers, and the tin content of the plating layers decreases layer by layer from inside to outside. The plating layer directly adjoining the surface of the steel wire base body has a high tin content, the adhesive force between the plating layer and the steel wire base body is strong, and the plating layer which has a high tin content can more effectively prevent the steel wire base body from rusting. The plating layers with the tin content gradually decreasing from inside to outside are combined closely with each other, and a strong adhesive force exists between the outermost plating layer with the relatively lowest tin content and tire rubber. |
