COMPOSITE MATERIAL OF NOBLE METAL

摘要

PURPOSE:To obtain a material having excellent properties such as durability and mechanical strength by superposing plural sheets of specific materials such as Pt-Rt and Pt and subjecting the same to composite working to a prescribed thickness. CONSTITUTION:Plural sheets of Pt-Ru and >=1 kind among Pt-Rh, Pt-Ir and Pt- Au are superposed and are subjected to 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 particularly the high-temp. durability is remarkably improved.
