| Abstract Scope |
The thermal conductivity of cast aluminum alloys is not as high as that of wrought aluminum alloys because the castability, especially fluidity, must be guaranteed. In the case of mobile devices such as smart phones, high-density components for better performance are used, which causes problems such as malfunction of the device due to heat generation. Therefore, it is necessary to develop a new alloy which has excellent thermal conductivity.
In this study, we investigated the effect of Si and Ca on thermal conductivity, fluidity, mechanical properties and corrosion. The effect of addition of Si was evaluated by dividing into the alloy group with 10 wt.% of Si and the alloy group with 0.5 wt.% of Si. The effect of calcium addition was evaluated by adding Mg+Al2Ca master alloy having different Ca contents to each alloy group. All test results were compared to the typical die cast alloy, 383 alloy. |
