PURPOSE:To obtain a material having excellent properties such as durability and mechanical strength by superposing plural sheets of Pt-20-40W% Rh and subjecting the same to composite working to a prescribed thickness. CONSTITUTION:A Pt-20-40W% Rh ingot is hot-forged and rolled to a thin material. A desired number of sheets of such metallic materials are superposed and are worked to a desired size by hot compression bonding and are further manufactured to the shape meeting applications. The mechanical strength is thus made higher than the strength of the conventional products of the same size and particularly the high-temp. durability is remarkably improved. |
