Nickel Titanium (Nitinol) Alloy Powder (NiTi) Description
Nitinol is a shape-memory alloy that offers unique properties such as shape memory, superelasticity, corrosion resistance, biocompatibility, gentle orthodontic force, and effective shock absorption. Due to these characteristics, it is extensively used in various biomedical, aerospace, and defense sectors.
Superelasticity in Nitinol is closely connected to its shape memory effect, with the main distinction being the environment's temperature. When the ambient temperature is above the alloy's transition temperature, Nitinol exhibits superelasticity. Conversely, when the temperature is below this threshold, the alloy displays its shape memory effect.
