Magnetic Shape Memory Alloy MSMA Magnetostrcitive Material

Magnetic Shape Memory Alloy Ni50-Mn28-Ga22 MSMA Magnetostrcitive Material


The Magnetic Shape Memory (MSM) in a Ni-Mn-Ga alloy was discovered in 1996 at MIT by Dr. Kari Ullakko and co-workers. The first MSMA alloy showed a strain of 0.2%. Since then, huge improvements have been achieved in the production process of MSM alloys as well as in the post-production treatments and training


The Magnetic Shape Memory Alloy(MSMA) is a new type of functional material that the heat-induced Martenitic phase transition occurs only under the temperature field, and also is stress-induced and magnetic-induced ones. The main component of the Magnetic Shape Memory Alloy (MSMA) is Ni-Mn-Ga, and the linear deformation rate reaches 10% at room temperature.

MSMA has great strain and high impetus and fast response speed and high efficiency. It is expected to become the preferred driving material in intelligent material systems.
