NOVELTY - Spoke alloy disc material comprises 50-55 %mass zinc, 10-12.5 %mass magnesium, 2-4.5 %mass copper, 2-4.5 %mass scandium, 0.5-0.8 %mass zirconium, 20.5-35.5 %mass iron, 0.2-0.8 %mass nickel, 0.5-0.8 %mass silicon, 0.5-0.8 %mass phosphorus diatomite, 1.5-2.5 %mass modified diatomite, and remaining of sulfur diatomaceous earth. USE - The spoke alloy disc material is used in a spoke disc (claimed). ADVANTAGE - The spoke alloy disc material has improved strength, hardness and toughness. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for preparing a spoke alloy disc material comprising (a) adding zinc, magnesium, copper, scandium, zirconium, iron, nickel, silicon, phosphorus diatomite, modified diatomite, and remaining of sulfur diatomaceous earth, (b) adding part of zinc, magnesium, and copper, heating up to melt, stirring and mixing, (c) gradually adding the remaining zinc, magnesium, and copper until it is completely melted, (d) continuously heating up until 2800-3000 degrees C, adding scandium, zirconium, and iron, (e) after melting, adding nickel, silicon, phosphorus diatomaceous earth, (f) stirring while cooling until the temperature reaches 800-1000 degrees C, adding modified diatomaceous earth and sulfur diatomaceous earth, stirring and mixing until completely melted; and (2) a method for preparing a spoke disc from the spoke alloy disc material comprising (i) injecting the prepared alloy material into the mold and cooling it to form, (ii) after forming, first transporting to the hot rolling device through the conveying device, and hot-rolling the formed spoke material slowly, and controlling the temperature of the hot rolling device, (iii) after the hot rolling is completed, subjecting to hydraulic cold rolling treatment to enhance the hardness of the formed wheel spoke plate, (iv) transporting to the punching device for punching and punching, (v) using computer numerical controlled (CNC) machine tools for cutting and polishing, and taking out the leftover material, (vi) injecting the anti-corrosion material into the spray gun and spraying on the outer surface of the metal to form the anti-corrosion film, and (vii) packing and encapsulating.
