The invention discloses a castable aluminum 
alloy material for a cylinder cover. The castable aluminum 
alloy material for the cylinder cover is characterized by comprising, by 
mass, 6.5%-7.5% of 
silicon, 0.55%-0.6% of 
zinc, 0.4%-0.5% of 
nickel, 0.2%-0.3% of 
vanadium, 0.22%-0.25% of 
magnesium, 0.2%-0.3% of iron, 0.1%-0.15% of 
tin, 45%-50% of 
scrap aluminum intermediate 
alloy powder, and the balance aluminum. Due to the facts that the proportions of the components of the alloy are optimized, the 
scrap aluminum intermediate alloy 
powder is used as the main component, and an appropriate amount of 
vanadium is added, the 
ductility of the aluminum alloy can be improved, and the 
castability and 
formability of the alloy are improved. According to the castable aluminum alloy material for the cylinder cover, a special treatment process is adopted, a refining agent made of porous materials is added, negative pressure is beneficial to degassing, and meanwhile materials in 
metal slag are separated; the prepared aluminum alloy material is high in strength and 
toughness, good in 
machinability and particularly suitable for manufacturing the engine cylinder cover.
