ABSTRACT:
Bimetallic coin or a medal and a method for producing the same, which is easy to form a ring and an insert composing the coin or the medal, yet costs low, and can assure a higher joining force between the ring and the insert.
The method includes processes for forming a ring by subjecting a first metal to blanking, annealing, and pickling, forming an insert thicker than the ring by subjecting a second metal to blanking and annealing, forming a thickened rim on each side, and an annular ridge around the circumferential surface of the insert, and pickling the insert, and joining the ring and the insert by causing plastic metal flow of the ridge of the insert into the inner circumferential surface of the ring through pressing the insert inserted in the center of the ring; and a bimetallic coin formed with the method.
