Abstract：

The influence of cooling rate on the mechanical properties and the amount of porosity was studied by adopting 100% silica sand (type A mild), 50% silica sand and 50% chromite sand (type B mold), and 100% chrmite sand (type C mold) and changing the length and thickness of A201 aluminum alloy plate and the riser size systematically. The result shows that cooling rate affects the the amount of porosity and mechanical properties of the castings. The tensile strength decreased with the amount of porosity. The cooling rate is faster in chromite sand mold, but also causes more porosity in castings.
