Copper Nitilon

Copper Ni-Ti wires consist of nickel, titanium, copper and chromium.

The addition of copper to the alloy enhances the thermal-reactive properties of the wire. Our Copper Ni-Ti 35°C.
The higher temperature transition (TTR), the lower the relative forces obtained by the wire. The Copper Ni-Ti series will   offer the force of choice and the wire size that will establish the case and treatment modality.

  • Unloading (spring back) properties facilitate tooth movement.
  • Due to the lower hysteresis of Copper Ni-Ti, the loading forces are smaller than their nickel titanium counterparts, making wire engagement in the bracket slot easier.
  • A unique unloading profile applies continuous forces, even at very small deflections.
  • More resistant to permanent deformation than other nickel-titanium wires.
  • Batch-to-batch consistency, with a very precise temperature range, ensures true heat activation and consistent, predictable results (Fig. B).
  • Easy to engage.


Copper Ni-Ti

The surface finish of the wires is smoother to maximize sliding characteristics.


35°C Copper Ni-Ti

With its TTR close-to-mouth temperature, is soft at room temperature to facilitate engagement. It falls within a very efficient force range when used in the larger round or all rectangular sizes.


Comparing Loading/Unloading

Fig. A – Initial deflection force is lower with Copper Ni-Ti, making it easier to engage severely malposed teeth. As the wire springs, back, more-consistent forces are maintained, even in minor deflections.


Transformation Temperature with Standard Deviations

Fig. B – Most so-called heat-activated wires have wide manufacturing tolerances, forcing their transformations to be set near room temperature. Thus they are fully active well before insertion in the mouth. The precision of Copper Ni-Ti allows the wire to be engaged before full activation at body temperature, but true
