ALUMINUM-MAGNESIUM-SILICON COMPOSITE MATERIAL AND PROCESS FOR PRODUCING SAME, AND THERMOELECTRIC CONVERSION MATERIAL, THERMOELECTRIC CONVERSION ELEMENT AND THERMOELECTRIC CONVERSION MODULE EACH COMPRISING OR INCLUDING THE COMPOSITE MATERIAL

摘要

Disclosed is an aluminum-magnesium-silicon composite material that contains an alloy comprising Al, Mg, and Si and can be used favorably as a material for a thermoelectric conversion module, and that has excellent thermoelectric conversion properties. The aluminum-magnesium-silicon composite material contains an alloy comprising Al, Mg and Si, and has an electrical conductivity (σ) of 1000-3000 S/cm at 300 K. This aluminum-magnesium-silicon composite material is favorable in the production of a thermoelectric exchange element as a result of having excellent thermoelectric conversion properties.
