Abstract
Provided are an aluminum-silicon-carbide composite having high thermal conductivity, low thermal expansion, and low specific gravity and a method for producing the composite. Provided is an aluminum-silicon-carbide composite formed by impregnating a porous silicon carbide molded body with an aluminum alloy. The ratio of silicon carbide in the composite is 60 vol % or more, and the composite contains 60-75 mass % of silicon carbide having a particle diameter of 80 μm or more and 800 μm or less, 20-30 mass % of silicon carbide having a particle diameter of 8 μm or more and less than 80 μm, and 5-10 mass % of silicon carbide having a particle diameter of less than 8 μm.
