Mg alloys on high thermal conductivity and mechanical properties are expected to replace the use of Al alloys in applications. Thermal conductivity influences the performance of alloys as a crucial function and is essential to extend the life of the materials due to uniform temperature distribution. In the present study, we studied effects of Sn addition on microstructure and mechanical properties of Mg-Sn-Ca alloys. Mg-Sn-Ca alloys prepared in crucible under the protection of mixed gas of CO2/0.5%SF6 using commercial stock. The melt was held at 700℃ for 20min and then poured into a mould. And then, as-cast Mg alloys were homogenized that held at 400℃ for 12hours. And homogenized alloys were hot-extruded into a plate that was 4mm in thickness and 50mm in width with a reduction ratio of 18:1. The electric and thermal conductivity of as-cast and as-extruded Mg alloys were investigated with addition of Sn and Ca elements.
