A kind of preparation process for the aluminum alloy materials for producing automotive hub is additionally provided in the application, including following step
Suddenly：
(1) it is spare to weigh following raw metal simple substance by weight：Iron 0.25-0.4%, silicon 4-6%, copper 2-8%, magnesium 0.5-
1.5%th, the aluminium of cobalt 0.3-1.0%, platinum 0.05-0.1%, osmium 0.002-0.004%, chromium 0.01-0.05% and surplus；
(2) smelting furnace is heated up, sequentially adds the raw material simple substance by the order of fusing point from high to low, treat that raw material simple substance is complete
After portion's fusing, 60-65min is kept the temperature, 10-15min is kept the temperature after being then air-cooled to 750-800 DEG C with stove again, obtains alloy molten solution；
(3) alloy molten solution is poured into preheated mold, is molded after alloy molten solution solidification, and the alloy cast ingot of formation is air-cooled
To room temperature；
(4) alloy cast ingot obtained is placed in progress homogenizing annealing processing in Muffle furnace；
(5) by step (4), treated that ingot casting is warming up to 600-650 DEG C in Muffle furnace, and keeps the temperature 30-35min, then with 15-
470 DEG C of temperature descending branch is kept the temperature 10-20min by the cooling rate of 20 DEG C/min, ingot casting is placed in glowing furnace afterwards, water cooling
To room temperature；
(6) by step (5), treated, and ingot casting is placed in Muffle furnace, is warming up to 200-220 DEG C, after keeping the temperature 10-15min, then is dropped
