HyFlex® CM
Pre-bendable like stainless steel with enhanced cyclic fatigue resistance vs conventional NiTi (manufacturer reports up to 300%, in-house bench data)

| 20/.04 | 0.20 | 4% | 500 | 2.5 |
| 25/.04 | 0.25 | 4% | 500 | 2.5 |
| 20/.06 | 0.20 | 6% | 500 | 2.5 |

CM-Wire has no shape memory at room temperature — files can be pre-bent like stainless steel to follow abrupt curvatures
Spiral lengthening under stress is a built-in safety feature that prevents wall binding and reduces fracture risk
Shape regenerates during autoclaving — visual inspection after autoclaving serves as a discard indicator
All files use the same motor settings: 500 RPM and 2.5 Ncm (EU IFU; US IFU specifies 2.4 Ncm)
Files may arrive slightly bent due to CM properties — correct by hand before use
A hybrid technique combining .04 and .06 tapers is the IFU-recommended approach
