The invention relates to a gear pump shaft sleeve with high wear resistance. The gear pump shaft sleeve with the high wear resistance takes aluminum as a base material and comprises the following components: not more than 0.50% of Si, 3.8-4.5% of Cu, 0.50-1.0% of Mn, 0.03-0.15% of Ti, 0.001-0.005% of Ni and 0.000-0.500% of Fe; and the gear pump shaft sleeve with the high wear resistance further comprises the following components: 1.7-2.3% of Mg and not more than 0.10% of Zn. According to the gear pump shaft sleeve with the high wear resistance, disclosed by the invention, the alloy takes the aluminum as the base material and contains Cu, Sn, Ni, Fe, Ti and other elements, and the gear pump shaft sleeve has higher strength, hardness and plasticity, and excellent performances of a sliding bearing after appropriate treatment; and the gear pump shaft sleeve with the high wear resistance has the advantages of small friction coefficient, stability, good wear resistance and strong impact resistance.
