Smartflex Wires

SAES offers SmartFlex Shape Memory Alloy (SMA) wires for actuators with a range of diameters from 20 microns to 500 microns. Custom diameters can also be provided upon request. Our SMA wires are available in Binary (NiTi) and Ternary (NiTiCu) alloys with different temperature ranges, commonly +95°C and +75°C. These wires are stabilized during the manufacturing process, ensuring high stability and fatigue resistance. They operate within a stress range of 50MPa to 400MPa, while typical operating forces range from 0.1 N to 40 N within the specified wire diameters. Moreover, typical operating strain conditions range from 1% to 5%.

To help users familiarize themselves with the material and facilitate initial actuator sizing, our SmartFlex brochure provides basic engineering rules and operating conditions. Additionally, our knowledgeable SMA team, with decades of experience in SMA materials and applications, is available to support all aspects of SMA-related assessments, from rapid feasibility reviews to prototyping, pre-development, and production.
