Skin material for clad material having at least one layer having a cast structure

摘要

The present invention relates to a skin material (3) for the clad material used in a method for manufacturing a clad material (1a-d) composed of a core material (2) and one or more skin materials (3) that are superposed on either one or both faces of the core material, the skin material (3) for the clad material (1a-d) comprising: the skin material (3) for the clad material is composed of one or more layers; each layer of the skin materials (3) is made of a metal different from the core material (2) in their component compositions; and at least one layer of the skin material (3) has a cast microstructure, when the skin material (3) is superposed on either of one or both faces of the core material (2).
