DescriptionNitinol wire
Nickel Titanium (NiTi) alloy wire, commonly known as Nitinol, is a unique material renowned for its remarkable properties, including shape memory and superelasticity. This alloy is composed primarily of nickel and titanium, typically in nearly equal atomic proportions, which gives rise to its distinctive characteristics:
- 1.Shape Memory Effect;
- 2.Superelasticity;
- 3.Biocompatibility;
- 4.Corrosion Resistance;
- 5.Thermal Responsiveness;
- 6.Versatility.
