1. Introduction: What Is Shape Memory Alloy Powder?
Shape Memory Alloy (SMA) powder is a category of smart material powders that can return to a pre-defined shape when subjected to specific thermal or mechanical stimuli. These powders are primarily composed of nickel-titanium (NiTi) but also include other alloys like Cu-Al-Ni and Fe-based SMAs.
B2B buyers, OEM manufacturers, and additive manufacturing (AM) specialists are increasingly sourcing SMA powders for:
- Precision component fabrication
- 항공우주 및 자동차 애플리케이션
