Platinum and it's alloys which own excellent characteristics such as corrosion resistance, high melting point, heat resistance and so on arewidely used for industry, for example, ammonia oxidation catalyst gauzes, thermocouples, temperature measuring resistance bulb, contact material. Noble metal alloys for springs are used for contact material. However, the fundamental data at high temperature are not enough. In this report, the tensile strength of Platinum-Rhodium alloys in the range of temperature 373-873K are examined and then compared with those of Platinum.
