Abstract：The casting process of a new high pressure oil channel of large and complex aluminum alloy cylinder block was introduced, and the influence of different core materials and processes on the density and performance of oil channel was studied. The new composite materials and process were verified by experiments. The results show that the materials have strong chilling effect, high thermal conductivity, specific heat capacity and density. The oil channel core made of this material not only has low air volume, but also has good air permeability and good dispersibility, and has high strength and refractoriness. This new process can not only guarantee the rigidity of oil channel core, but also ensure its good permeability, which can satisfy the casting and forming of various large aluminum alloy cylinder block with deep holes.
