The invention relates to an aluminum alloy and a part prepared from the aluminum alloy. The invention relates to an aluminum alloy comprising: 7 to 9% by weight of silicon (Si), 0.15 to 0.45% by weight of chromium (Cr), 0.1 to 0.3% by weight of vanadium (V), at least 0.01% by weight of strontium (Sr), 0.1 to 0.2% by weight of titanium (Ti), 0 to 0.5% by weight of manganese (Mn), 0 to 0.8% by weight of iron (Fe), the balance being aluminum and unavoidable impurities. 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)、0.15‑0.45重量%的铬(Cr)、0.1‑0.3重量%的钒(V)、至少0.01重量%的锶(Sr)、0.1‑0.2重量%的钛(Ti)、0‑0.5重量%的锰(Mn)、0‑0.8重量%的铁(Fe),余量为铝和不可避免的杂质。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。
