PROBLEM TO BE SOLVED : To produce an inexpensive, highly functional alternative rare metal by adding CNTs (carbon nanotubes) to a general metal, and to achieve the improvement of its function and the resource conservation by adding the CNTs to a rare metal. SOLUTION : CNTs are uniformly dispersed into a metal to form into a base by applying a folding refining process. At this time, by controlling the addition amount of the CNTs and the folding frequency, the characteristics of the mixed metals are changed, and this invention is used as the substitutional material for various kinds of rare metals.
