Development and Property Evaluation of Low-Si Aluminum Casting Alloys for Thermal Dissipation

Article Preview

Abstract:

To develop an aluminium alloy which may combine high thermal conductivity and good castability and anodizability, Al-(0.5~1.5)Mg-1Fe-0.5Si and Al-(1.0~1.5)Si-1Fe-1Zn alloys were assessed as potential candidates. The alloys exhibited 170~190% thermal conductivity, 60~85% fluidity, and equal or higher ultimate tensile strength compared to those of ADC12 alloy.
