Stainless Steel
Forged from highest quality medical grade steel
Strict corner-radius and torque controls ensure optimal wire to bracket interaction
Stress relieved for superior tensile strength with less brittleness
Heat treated to slightly higher tensile strength
Permanent Centerline Mark:The distinct upper and lower gable mark the arch wire between the central incisors, prevents asymmetry problems. It also eliminates the need for time-consuming cinch-back bends. 
 
NiTi
Fully active at room temperature
Exhibits excellent springback
Gentle to patients, but powerful enough to align even the most challenging cases
Moderate forces are an excellent choice for all treatment phases
