Mg5In

Mg5In is an intermetallic compound combining magnesium and indium, belonging to the ceramic/intermetallic materials class. This is a research-phase material studied primarily for its potential in lightweight structural applications and electronic/thermal management systems where magnesium's low density can be leveraged alongside indium's electronic properties. The material remains largely experimental, with limited industrial deployment; it represents exploration within the broader magnesium-rare element alloy family for specialized aerospace, electronics, and thermal interface applications where conventional Mg alloys or pure ceramics fall short.
