The invention provides an aluminum alloy profile for a hot-forging control arm and a processing method and application thereof, and the aluminum alloy profile for the hot-forging control arm comprises the following components in percentage by weight: 1.05-1.25% of Si, Filt, 1.05-1.25% of Al, 1.05-1.25% of Al, 1.05-1.25% of Al, 1.05-1.25% of Ti, 0.3%, Cult; the alloy comprises the following components in percentage by weight: 0.1% of Mn, 0.50%-0.65% of Mg, 0.13%-0.20% of Cr and Nilt; 0.05% of Zn < lt >; 0.05%, Tilt; the total amount of Mn and Cr is 0.70%-0.80%, and Mg/Si is 0.5%-0.9% according to the mass ratio of the Mn to the Cr. According to the aluminum alloy profile, the prefabricated profiling design is adopted, one-time flattening and bending procedures can be reduced, the forging deformation amount is reduced, the generation of forged coarse-grain rings is better inhibited, and the production cost is reduced while the quality is improved. According to the invention, the chemical components of the aluminum alloy are optimized, so that the obtained aluminum alloy profile can obtain higher comprehensive properties, such as strength, hardness and structure uniformity, and is free of coarse grain rings and the like.

    本发明提供了一种热锻控制臂用铝合金型材及其加工方法与应用,本发明热锻控制臂用铝合金型材,按重量百分比计,包括以下组分:Si 1.05%‑1.25%,Fe<0.3%,Cu<0.1%,Mn 0.50%‑0.65%,Mg 0.70%‑0.95%,Cr 0.13%‑0.20%,Ni<0.05%,Zn<0.05%,Ti<0.05%,余量为Al,其中Mn和Cr的总量为0.70‑0.80%,按质量比计,Mg/Si为0.5‑0.9。本发明的铝合金型材采用预制仿形设计,可减少一次压扁折弯工序,减少锻造变形量,更好的抑制锻造粗晶环的产生,提高质量的同时降低生产成本。本发明优选了铝合金的化学组分,所得铝合金型材可获得更高的综合性能,如强度、硬度和组织均匀性、无粗晶环等。
