Disclosed is a composite of a metal alloy and a ceramic resin. The composite of a metal alloy and a ceramic resin of the present invention comprises: a metal alloy having groove and protrusion undercuts which have an average surface roughness of 80-150 μm and which are formed by removing grease on a surface of the metal alloy using a surfactant and by etching the degreased surface using an aqueous solution of at least one acid selected from hydrochloric acid, sulfuric acid, nitric acid, and formic acid; and a ceramic resin material containing 30-70 wt% of at least one resin selected from polypropylene, polyamide, polyphenylene sulfide, polyacetyl, polycarbonate, polyester, and polyphenylene oxide, 20-60 wt% of silicon carbide, 5-7 wt% of an inorganic filler, and 3-5 wt% of a dispersant, wherein the ceramic resin material is integrated with the surface of the metal alloy having the groove and protrusion undercuts by means of injection molding. Due to the integration of the ceramic resin having a heat radiation function and the metal alloy, the present invention can be used for various electronic products, home appliances, medical devices, automotive structural parts, vehicle-mounted products, construction material parts, and other structural parts, exterior parts, LED lighting devices, and the like. |
