The invention relates to an aluminum alloy, a part prepared from the aluminum alloy and a vehicle comprising the part. The invention relates to an aluminum alloy comprising: 3-6% by weight of silicon, 6-18% by weight of zinc, 0-3% by weight of copper, 0-3% by weight of magnesium, 0-0.3% by weight of chromium, 0-0.6% by weight of manganese, 0-0.3% by weight of vanadium, at least 0.01% by weight of titanium, at least 100 ppm of strontium, 0-1% by weight of iron, the balance being aluminum and unavoidable impurities wherein the chromium content is not less than 0.2% by weight when manganese is not present; when chromium does not exist, the content of manganese is not less than 0.3 wt%. According to the aluminum alloy, the heat treatment process after casting can be omitted in the machining process, energy conservation and emission reduction are facilitated, and parts prepared from the aluminum alloy can meet the mechanical property requirements of automobile structural castings.

    本发明涉及一种铝合金以及采用其制备的零部件与包括该零部件的车辆。所述铝合金包含:3‑6重量%的硅、6‑18重量%的锌、0‑3重量%的铜、0‑3重量%的镁、0‑0.3重量%的铬、0‑0.6重量%的锰、0‑0.3重量%的钒、至少0.01重量%的钛、至少100ppm的锶、0‑1重量%的铁,余量为铝和不可避免的杂质,其中当锰不存在时,铬的含量不低于0.2重量%;当铬不存在时,锰的含量不低于0.3重量%。本发明的铝合金在加工过程中可以免除铸造后的热处理工艺,有利于节能减排,并且由其制备的零部件能够满足汽车结构铸件的力学性能要求。
