Abstract
The present invention provides a composite material suitable for thermal plastic processing, and having a coating layer that includes a heat-resistant resin having a melting point or pyrolysis temperature of 150° C. or more on the surface of at least one side, and preferably both sides, of a magnesium (alloy) plate. The heat-resistant resin is preferably a thermosetting resin based on polyimide. By using the composite material of the invention, processing with a high degree of processing, such as deep drawing and formation of complex ribs and bosses, can be achieved easily by thermal plastic processing. The present invention also provide a magnesium (alloy) plastic-processing product obtained by plastic processing by using the composite material.
