The purpose of this study is investigating for influence of difference process on material development for non-contact torque sensor utilizing magnetostriction ring. We applied FeGa polycrystalline magnetostrictive material which has been studied by the author's grope. FeGa polycrystalline has low mechanical strength. However, recently We had developed FeGa polycrystalline which have high mechanical strength by adding Al, ZrC. In this study, We use this material and make magnetstrictive ring by two processes. One is Cu-mold cast method, the other is Sintering method using Spark Plasma Sintering. Samples made by these processes indicate different magnetic property. And magnetstorictive ring make by these processes, masured each characters of applied torque sensitivity.
