Magnetic Shape Memory Alloy Introduction
Latest company news about Magnetic Shape Memory Alloy Introduction

Magnetic shape memory alloys are ferromagnetic materials that generate force and motion under moderate magnetic fields. The typically single crystalline alloys made from nickel, manganese and gallium are able to generate 6% strain under external loads. And they do this with frequencies into the low kilohertz range.
