Shape Memory Nitinol Wire

Introduction of Shape Memory Nitinol Wire

The crystal structure of the nickel-titanium alloy is different when temperature below 40 ° C or above      40 ° C , but when the temperature is changed up and down at 40 ° C, the alloy shrinks or expands, causing its morphology to change. Here, 40 ° C is the "metamorphic temperature" of the nickel-titanium memory alloy. Different alloys have their own metamorphic temperatures.

Features

1. large bending rent,high plasticity

2. Restore the previous shape above the memory temperature

3. Physical properties: When the temperature reaches to a certain value, the crystal structure inside the material changes, resulting in a change in shape.

4. Tensile strength: 850 MPa

5. Yield strength: 195 ~ 690 MPa

6. Elongation: 25 to 50%
