The invention discloses a high-strength aluminum alloy profile for a fire-fighting truck and a preparation method of the profile. The aluminum alloy profile is prepared from components as follows: Zn,Cu, Mg, Mn, Si, Fe, Cr, Ti, Li, Ni, Zr, V, Nb, Y, Ce, Nd and the balance of Al and inevitable impurities. According to the high-strength aluminum alloy profile for the fire-fighting truck and the preparation method of the profile, the obtained aluminum alloy profile is low in density and high in strength and hardness, has the good corrosion resistance, wear resistance and machinability, has the long service life and the stable performance and effectively improves the performance of the fire-fighting truck. 本发明公开了种消防车用高强度铝合金型材及其制备方法，所述铝合金型材包括以下组分：Zn、Cu、Mg、Mn、Si、Fe、Cr、Ti、Li、Ni、Zr、V、Nb、Y、Ce、Nd，其余为Al及不可避免的杂质。本发明提出的种消防车用高强度铝合金型材及其制备方法，得到的铝合金型材密度小，强度与硬度大，具有良好的耐腐蚀性、耐磨性和加工性能，其使用寿命长，性能稳定，有效改善消防车性能。
