  • Patent number: 11400766
    Abstract: Disclosed are a cable bead and a tire. The cable bead includes a core wire located at the middle position of the bead and at least one layer of outer winding wires wound around the core wire, each layer of outer winding wires being evenly wounded along the circumferential direction of the core wire, where the cross section of the outer winding wires is a flat surface having a major axis and a minor axis; the major axis is perpendicular to the radial direction of the cross section of the bead, and the minor axis is parallel to the radial direction of the cross section of the bead; the outer winding wires are in surface contact with the core wire; and when there are at least two layers of outer winding wires, a line contact is formed between the layers of outer winding wires.

  • Patent number: 11020781
    Abstract: Disclosed are a metal wire, a manufacturing method therefor, and a tire. The metal wire is made by twisting a filament; an outer peripheral surface of the filament is covered with a Cu-M-Zn alloy coating; the outer peripheral surface of the filament is also covered with a Cu—Zn alloy coating; the metal wire is made of at least one filament; an area covered by the Cu-M-Zn alloy coating is 10%-90% of an area of the outer peripheral surface of the filament, and the rest is the Cu—Zn alloy coating; M in the Cu-M-Zn alloy coating is selected from one or two of Co, Ni, Mn, or Mo; the mass fraction of Cu in the Cu-M-Zn alloy coating is 58%-72%, the mass fraction of M in the Cu-M-Zn alloy coating is 0.5%-5%, and the balance in the Cu-M-Zn alloy coating is Zn and inevitable impurities.
