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.

A hybrid cable having a core and a wrap; the core made from a carbon fiber yarn or bundle of carbon fiber strands or yarns; and the wrap made of a plurality of metal wires helically wrapped around the core, the plurality of metal wires laid side by side without crossing each other. The fibers, yarns, or core may be treated with polymeric sizing, adhesive, or binder. The wire may be steel and may have a coating such as brass or zinc plating, or a polymeric coating or treatment. The hybrid cable is useful for reinforcing composite articles such as belts, track, or hose.

A steel cord for rubber reinforcement comprises a first group of core filaments (105) having a number of m and a second group of sheath filaments (110) having a number of n, m is three or four, the core filaments (105) are forming a helix, the core filaments (105) are not twisted together and being substantially parallel or the core filaments (105) have a twist pitch being more than 300 mm; the second group and the first group are twisted with each other, and the sheath filaments (110) are forming a flattened helix in the same direction of the helix of the core filaments (105), and the sheath filaments (110) have a cord twist pitch, at any cross-section of the steel cord, at least one interstice between two adjacent core filaments (105) is present. The steel cord has improved abrasion resistance and can contribute to the reduction of the weight of the tire.

A brass-plated steel cord 1A is immersed in an organic solvent 13. The steel cord that was immersed in the organic solvent 13 is immersed in an aqueous alkaline solution 22. Next, the steel cord 1A that was immersed in the aqueous alkaline solution 22 is immersed in an aqueous silane coupling solution 32. Finally, the steel cord 1A that was immersed in the aqueous silane coupling solution 32 is heated. Thus is manufactured a steel cord 1B equipped with the silane coupling agent, wherein the silane coupling agent is excellently bonded to the surface.

A composite article comprising at least one metal reinforcement element embedded in a polymer material, said metal reinforcement element being at least partially coated with an adhesion promoting layer, said adhesion promoting layer being interposed between said metal reinforcement element and said polymer material, characterized in that said adhesion promoting layer comprises an acid anhydride-grafted polyolefin and a phenolic antioxidant.

A motor vehicle tire is reinforced by at least one carbon steel band that has a very low carbon content and high strength in the work-hardened state The carbon steel comprises (% by weight) between 0.05% and 0.4% of carbon, between 0.5% and 4% of manganese, between 0.1% and 2.5% of silicon, optionally (i) less than 1.5% of aluminium, (ii) less than 0.5% of each of the metals boron, chromium, cobalt, copper, molybdenum, nickel, niobium, titanium, tungsten, vanadium, and zirconium, and (iii) less than 0.05% of each of the elements phosphorus, sulfur, nitrogen, or rare earth, and the rest is made up of iron and inevitable impurities resulting from the smelting. The microstructure of the work-hardened carbon steel is mainly martensitic or ferritic-martensitic. The strength, denoted Rm, of the strip is greater than 1200 MPa and its elongation at break, denoted At, is between 1% and 5%.
