Cuniti archwires are better than other archwires.

The addition of copper to traditional nickel titanium enhances thermal reactive properties and consistency of forces. Superior resistance to permanent deformation than NiTi.The inclusion of copper in the nickel-titanium alloy accentuates the thermal properties and working characteristics of the wire. The lower hysteresis of TruFlex Copper provides a lighter tactile “feel” of the wire at room temperature which translates to additional flexibility providing for easier placement on cases with crowding conditions.
