Introduction
The global Shape Memory Alloys (SMA) market is experiencing robust growth as industries increasingly adopt smart materials for high-performance applications. According to Stratview Research, the Shape Memory Alloys market is likely to grow at a promising CAGR of 11.2%, reaching US$ 18.8 billion by 2028. The expanding use of SMAs in medical devices, aerospace components, and smart technologies continues to drive this upward trend.
Key Features
SMAs are distinguished by their ability to return to a pre-defined shape when heated, owing to reversible phase transformation. They offer exceptional superelasticity, biocompatibility, corrosion resistance, and high fatigue life. Nickel–titanium (nitinol) remains the most widely used SMA due to its superior performance, followed by copper- and iron-based alloys.
