The invention relates to an aluminum alloy and a part prepared from the aluminum alloy. The aluminum alloy comprises, by weight, 7%-9% of silicon (Si), 0.2%-0.7% of manganese (Mn), 0.09%-0.4% of iron (Fe), 0.1%-0.3% of vanadium (V), 0.1%-0.2% of titanium (Ti), 0.01%-0.03% of strontium (Sr) and the balance aluminum and inevitable impurities, and the weight ratio of the manganese (Mn) to the iron (Fe) is not lower than 1. 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 achieve the expected mechanical property.
本发明涉及一种铝合金以及以及采用其制备的零部件。所述铝合金包含:7‑9重量%的硅(Si)、0.2‑0.7重量%的锰(Mn)、0.09‑0.4重量%的铁(Fe)、0.1‑0.3重量%的钒(V)、0.1‑0.2重量%的钛(Ti)、0.01‑0.03重量%的锶(Sr),余量为铝和不可避免的杂质,其中锰(Mn)和铁(Fe)的重量比不低于1。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达到所期望的力学性能。
