High-strength abrasion-resistant metal product

The invention discloses a high-strength abrasion-resistant metal product. The high-strength abrasion-resistant metal product comprises an alloy layer and two abrasion-resistant plastic layers, wherein the upper surface and the lower surface of the alloy layer are covered with the two abrasion-resistant plastic layers respectively, the two abrasion-resistant plastic layers have the same structural components, and the alloy layer accounts for 75-85% of the total weight. The alloy layer is prepared from, by weight, 0.1-0.5 part of lanthanum, 7-10 parts of copper, 23-28 parts of iron, 8-12 parts of aluminum and 19-23 parts of silicon. Each abrasion-resistant plastic layer is prepared from, by weight, 3-6 parts of polytetrafluoroethylene, 8-12 parts of molybdenum disulfide, 8-12 parts of high abrasion-resistant carbon black and 5-9 parts of polyvinyl acetal. Due to the joint action of the alloy layer and the abrasion-resistant plastic layers, the abrasion of the obtained metal product is smaller than or equal to 0.03g/kg*h, Mohs hardness is 9.25-10, and high strength and abrasion resistance of the metal product are effectively improved.
