Memory alloy is a martensitic phase change alloy with regular atomic arrangement and less than 0.5% volume. The alloy is deformed by external forces. When the external force is eliminated, the original shape can be restored at a certain temperature. Because it has more than one million recovery functions, it is called a "memory alloy"
The breast support pattern is located in the most abundant lymph nodes of the breast. Due to the superelasticity of the nickel-titanium memory steel ring, the "zero compression" of the breast can improve blood flow, microcirculation, nutrient supply, metabolism and activation of breast tissue cells.
Nitinol shape memory material is a special material that integrates sensing and driving. Nitinol shape memory alloy is an important part of Nitinol shape memory material. Nickel-titanium shape memory alloy is an alloy that undergoes low-temperature plastic deformation and changes its shape to another shape in a certain initial state. The temperature is increased by means such as heating and then changed to the original shape.
