Abstract

The strain gauge factor K at room temperature, the electrical resistivity ρ at 20°C and its mean temperature coefficient Cf, and the mean thermal electromotive force Emf in the temperature range of 0° to 40°C have been measured with wires of Fe-Cr alloys containing 0∼50% chromium in a cold-worked state of about 98% reduction. It has been found that the largest value of K obtained is 6.2 for the Fe-Cr alloy containing 20% chromium, ρ, Cf and Emf of which are 44.6 μΩ-cm, 32.7×10−4 and 11.0 μV/°C, respectively.
