The present invention relates to a pressing jig for bonding double metal guaranteed with long-life characteristics and properly enduring high temperature and high pressure to be used in a semi-solid diffusion bonding method. The pressing jig comprises a lower jig of a square plate shape, where a lining material and a base material are mounted to be stacked on an upper surface; a disk-shaped upper jig arranged on the upper surface of the lower jig and has a concave adhesion groove on the lower surface; a supporting plate of a square plate shape, arranged on the upper surface of the upper jig, having an insertion groove where the upper surface of the upper jig is inserted to the lower surface, and formed in the same size with the lower jig; and pressurization parts respectively formed between four sides of the supporting plate and four sides of the lower jig corresponding thereto, and pressurizing the supporting plate in four areas toward a lower part in corresponding to the lower jig. |
