The invention discloses a high-wear-resistance aluminum alloy material suitable for a liquid die forging process, which is characterized by comprising the following components in percentage by weight: 5.5-7.5% of Si; less than or equal to 0.3% of impurities; 0.5% to 1.5% of Cu; 0.3% to 0.6% of Mg; 0.5 to 1.0 percent of Zn; 0.2%-0.5% of Mn; 0.01%-0.04% of Sr; 0.1 to 0.3 percent of La; 0.085 to 0.2 percent of Ce; and 0.1 to 0.6 percent of Zr. Al is the balance. The prepared high-wear-resistance aluminum alloy material suitable for the liquid die forging process has the elongation being larger than 6% and the hardness being larger than 140 HB and meets the liquid die forging process characteristics, and the specific meeting process characteristics are that the ultra-low speed and high pressure are used for solving the problems of segregation and poor wear resistance caused by insufficient hardness.
