Nitinol can return to its preset shape when heated to a specific transformation temperature (typically adjustable between -50°C to 100°C). This effect arises from reversible phase transformation between austenite (high temperature phase) and martensite (low temperature phase), with a strain recovery of over 8%, far exceeding conventional metals.
In the austenite phase, Nitinol can withstand up to 8% strain and fully recover its shape upon unloading, far exceeding the elastic limit of traditional metals (e.g., stainless steel <1%). Its stress-strain curve exhibits a nonlinear plateau, ensuring flexibility and fatigue resistance in dynamic environments.
Nitinol shows excellent corrosion resistance in acidic, alkaline, and chloride environments (e.g., seawater, body fluids). A naturally formed titanium oxide (TiO₂) layer offers additional protection, outperforming many traditional alloys against pitting and crevice corrosion.
With surface passivation (e.g., electropolishing, oxidation), Nitinol significantly reduces nickel ion release, complying with ISO 10993 biocompatibility standards, and is suitable for demanding biological environments.
With tensile strength typically ranging from 1000–1500 MPa (optimized via heat treatment) and elongation over 20%, Nitinol combines high fatigue resistance (withstands millions of cycles), making it ideal under high stress and dynamic conditions.
Maintains stable mechanical properties from -100°C to +200°C, suitable for extreme temperature environments.
Through precise adjustment of Ni-Ti ratio, impurity levels, and heat treatment, transformation temperatures can be customized from -50°C to 100°C for diverse applications.
In the martensitic phase, Nitinol offers excellent energy absorption, ideal for vibration-damping applications.
Each batch of Nitinol undergoes thorough testing, including:
Chemical Composition Analysis: Impurity levels meet ASTM F2063 standards.
Mechanical Property Testing: Tensile tests (strength, elongation), fatigue life tests, and hardness tests (HV).
Transformation Temperature Testing: Differential Scanning Calorimetry (DSC) determines As/Af and Ms/Mf with precision.
Surface Quality Inspection: Scanning Electron Microscopy (SEM) verifies surface roughness (Ra<0.1μm) and defect-free surfaces.
Dimensional Accuracy Verification: Coordinate Measuring Machines (CMM) ensure micron-level tolerances.
Certified under ISO 9001, products comply with ASTM F2063 (medical Nitinol) and ISO 10993 (biocompatibility).
