Medical-grade Nitinol tubing meets ASTM F2063 standards, ensuring it is suitable for long-term implantation in the human body. Its ability to maintain flexibility while providing strong mechanical support makes it superior to traditional metal tubing, such as stainless steel, which lacks shape memory properties.
Nitinol tubing is also widely used in robotics, aerospace, and industrial fluid management applications, where precise movement and adaptability are required.
