Explanation materials on the basic knowledge of Nitinol - Detailed explanation of phase transformation, measurement methods for transformation temperature, superelasticity, and shape memory effect, including the underlying principles.
Shape Memory Alloys (SMA) are unique metals that can return to their original shape when they reach a specific temperature. SAES's group company, memry, boasts the world's largest production capacity of Nitinol (Ni-Ti) and has nearly 30 years of experience in low-invasive medical devices such as stents, catheters, and guidewires. Nitinol often cannot directly apply the characteristics, design concepts, and manufacturing processes of conventional metal materials, requiring a wealth of knowledge and expertise in handling. Please utilize this document to expedite the learning process for companies and engineers who are using Nitinol alloys for the first time.
