Basic Knowledge of Nitinol Shape Memory Alloy Sheet
The main material of nitinol shape memory alloy sheet, foils, and strips is nickel titanium alloy. Nickel titanium alloy sheets are well suited for laser cutting, etching, stamping, and electrical discharge machining (EDM). Efficient processing and surface treatment technologies form a smooth lightly oxidized surface. Nickel titanium alloy materials currently have prominent performance and application value in the medical field. As a two-dimensional structure, sheets differ from wires and tubes, offering design options such as stamping, punching, and deep drawing.
- nitinol shape memory alloy sheet with shape memory effect (SME) and superelasticity, composed of ~50% Ni and ~45% Ti.
Temperature of Nitinol Shape Memory Alloy Sheet
- Transition temperature (Af): -50℃ ~ +150℃ (customizable for specific applications).
- Service temperature: -20℃ ~ +120℃ (continuous use); short-term up to +150℃.
