The invention discloses a high-strength wear-resistant aluminium alloy material and a preparation method thereof. The high-strength wear-resistant aluminium alloy material is prepared from the components in percentage by weight: 6.50-10.50% of Cu, 2.50-4.50% of Zn, 0.21-0.25% of Mn, 0.40-0.60% of B, 0.34-0.38% of Ni, 0.08-0.12% of Zr, 0.11-0.15% of Ti, 0.02-0.05% of Mo, 0.22-0.26% of W, 0.05-0.09%of rare earth elements and the balance of aluminium and other inevitable impurities. According to the preparation method of the high-strength wear-resistant aluminium alloy material, by designing thespecific alloy components, the problems of poor wear resistance and strength of an aluminium alloy material are solved, so that the aluminium alloy material has high strength, high wear resistance and excellent tensile strength at the same time.
