The effects of applied pressure, superheat and silicon content on the fluidity of Al-Si alloy during squeeze casting were investigated. The Fluidity of Al-7.0wt%Si alloy during squeeze casting was increased with applied pressure up to 60 MPa, meanwhile it rather decreased beyond that. Therefore, the optimum squeeze casting pressure was 60 MPa. The fluidity was increased with superheat up to 150°C. On the other hand, it rather decreased at the superheat of 200°C. The fluidity of Al-Si alloy during squeeze casting was decreased with silicon content in the range of 0.0~3.0wt%, increased in the range of 3.0-13.0 wt%. The fluidity of Al-15.0 wt%Si alloy was lower than that of Al-13.0 wt%Si alloy.
