Giant magnetostrictive material

Giant magnetostrictive material: 1. Tb-Dy-Fe 2. Fe-Ga

       Giant magnetostrictive material is an alloy mainly composed of Tb-Dy-Fe and Fe-Ga. It can change electrical energy into mechanical action or vice versa because of its merit as being sensing and actuating material. Demanding only low voltage, the strain it can produce is 40 times higher than that of the traditional magnetostrictive materials. The giant magnetostrictive material can be used in the micro displacement drive, robot, automatic control, ultra precision machining, infrared laser scanning, and the camera shutter, linear motor, intelligent wing, fuel injection system, miniature pumps, valves, sensors, etc.

        YOUK enterprise successfully accomplished the patented technique of producing grain-oriented Tb-Dy-Fe and Fe-Ga giant magnetostrictive materials and products with the famous Scientific research institutes, established complete production facilities wire an annual output of 1,000kg and YOUK engineering technology research center. Combined with vacuum melting, directional solidification(Bridgman method and free standing zone melting)and series of state-of-art technique, the production conditions and crystallization process are strictly controlled, products of high performance and stable quality can be supplied in large quantities to meet the customers

requirement.
