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.

Characteristics of the Magnetic Shape Memory Alloy for commercial use

• Typical strain up to 6%
• Blocking stress up to 3.5 MPa
• Magnetic Õeld for maximum strain of about 500 kA/m
• Full strain up to about 2 MPa load
• Work output per unit volume of about 150 kJ/m³
• Energetic eÞciency up to 90%
• Reaction times of about 1 ms (in MSM actuators)
• Hysteresis between stress or magnetic Õeld and strain (material damping)
• Internal friction
• Magnetic and thermal activation are both possible
• Operating temperatures: -40 °C to 60 °C
• Change in magnetic permeability and electric resistivity during deformation
