About
Nickel-Titanium (NiTi) alloy, commonly known as Nitinol, is a highly versatile shape memory alloy with a near-equiatomic composition of nickel and titanium. It is renowned for its unique properties, including shape memory, superelasticity, high fatigue resistance, and biocompatibility. The material undergoes reversible phase transformations, allowing it to recover its original shape after deformation when exposed to specific temperature changes. These characteristics make NiTi ideal for applications requiring flexibility and precision, such as medical implants, actuators, and components in aerospace and robotics. Additionally, NiTi exhibits corrosion resistance and excellent mechanical performance, further enhancing its suitability for demanding environments. Its behavior can be fine-tuned by adjusting composition and thermal treatment, offering adaptability across various industries.
