1. Plural of nitinol; alloys of nickel and titanium that exhibit shape-memory and superelastic properties, used in medical devices, aerospace, and engineering applications.
Usage: technical; materials science

Examples

• Nitinols are widely used in orthodontic wires because they return to their original shape when heated.
• Medical stents made from nitinols can expand and contract safely inside blood vessels.
• Engineers prefer nitinols for applications requiring flexibility and durability.
• The superelastic properties of nitinols make them ideal for eyeglass frames.
• Nitinols demonstrate remarkable resistance to fatigue compared to conventional metal alloys.
