Patent ID: 8367210

Claim:
An aluminum alloy-and-resin composite comprising: a shaped aluminum alloy material that has been subjected to a dipping process in which it is dipped in a 3 to 10% hydrazine monohydrate aqueous solution at 40 to 70° C. forming fine recesses and adsorbing nitrogen-containing compounds attributable to hydrazine on a surface of said shaped aluminum alloy, said fine recesses having a diameter of 30 to 300 nm on the surface of said shaped aluminum alloy material, said fine recesses having been formed by a basic reaction, wherein after the dipping process, the shaped aluminum alloy material is dried with warm air of room temperature to 80° C.; and a thermoplastic resin composition integrally bonded to the surface of said shaped aluminum alloy material by injection, said thermoplastic resin composition containing polyphenylene sulfide as a component.
