Abstract
A composite characterized by comprising an aluminum alloy shaped item having a surface roughness of 5 to 50 .mu.m or more, the surface provided with 1 .mu.m or less fine depressions or protrusions, and a thermoplastic resin composition composed mainly of a polyphenylene sulfide or polybutylene terephthalate resin whose average of lengthwise and crosswise linear expansion coefficients is in the range of 2 to 4.times.10.sup.-5.degree. C..sup.-1, the thermoplastic resin composition penetrating and anchored in the depressions or protrusions. The thermoplastic resin composition is not easily detached from the aluminum alloy shaped item. Thus, in, for example, electronic equipments and household electrical appliances, the advantage of metallic cage body can be reconciled with the advantage of synthetic resin structure. This composite can ensure high production efficiency and is suitable for mass production. Further, morphology and structure designing thereof can be accomplished freely.
