PURPOSE:To obtain a material having excellent durability and mechanical strength by superposing plural sheets of 1 or >=2 kinds of materials formed by plating Rh on a specific material consisting of Pt. etc. and subjecting the superposed materials to composite working to a desired thickness. CONSTITUTION:Plural sheets of 1 or >=2 kinds of materials formed by plating Rh to Pt, Pt-Rh, Pt-Ir, Pt-Ru and Pt-Au are superposed and are worked by hot compression bonding to a desired size. The worked material is further manufactured into the shape meeting applications. The mechanical strength is made higher than the strength of the conventional products of the same size and marticularly the high-temp. durability is remarkably improved. |
