## Key Features

HyFlex CM

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

HyFlex EDM

EDM + CM-Wire with regenerative memory — manufacturer reports enhanced fatigue resistance (bench data; figures vary by comparator and test setup)
