1. A wire of a nickel-titanium alloy having a permanent set of less than 5% in length when 11% strain is applied to the wire, the wire having a modulus of at least 53 GPa when 200 MPa of stress is applied to the wire, wherein the modulus is calculated based on a tensile stress and a tensile strain of the wire.
