Disclosed is a method for making aromatic metal products which have splendid appearance with various colors and emit fragrance. Suitable for use in fancy goods, the aromatic metal products are prepared by sintering a pre-molded body between 900 and 1,400° C. to give a porous metallic sintered body with a porosity of 10-20%; cleansing the porous metallic sintered body to remove impurities therefrom; etching the cleansed sintered body in a vacuum furnace and plating it with Ti by sputtering; and introducing fragrance into the Ti-plated sintered body. The pre-molded body is made by pressuring a mixture containing a metal powder with a mean particle size of 100 μm or greater and a binder at room temperature under a pressure of 100-600 MPa. The introduction of a perfume can be achieved in a forcible manner in which the sintered body is charged in a vacuum bath to remove inner air therefrom, followed by the infiltration of the perfume. Alternatively, the sintered body may be simply immersed in a perfume liquid to naturally infiltrate the perfume thereinto. The porous metal may be based on a material such as stainless steel, nickel, copper-zinc, gold or silver. |
