Galfenol is an alloy made primarily of iron and gallium, known for its unique magnetic and mechanical properties. It is a type of magnetostrictive material, which means it can change shape or dimensions under the influence of a magnetic field. This property makes Galfenol useful in various applications, such as sensors, actuators, and energy harvesting devices. The alloy is noteworthy for its relatively high magnetostrictive response compared to other traditional materials.
