(57) [Summary] (Modifications) [PROBLEMS] Non-magnetic metallic glass for strain gauges containing at least 50% or more by volume of amorphous material, having a gauge factor of 2 or more, and having high strength and high corrosion resistance. Provision of alloys. A general formula Cu 100-a-b-c M a X b (M is one or two or more elements of Zr, RE and Ti, X is one or two or more elements of Al, Mg and Ni, and the composition ratios a and b are atomic%. 5 ≦ a ≦ 65.0, 0.001 ≦ b ≦ 40, and 5 ≦ a + b ≦ 70) and a small amount of impurities, containing 50% or more by volume of amorphous material, having a gauge factor of 2 or more, and having high strength and high corrosion resistance. Glass alloy. |
