Because of its low Young's modulus, the force produced when GUMMETAL is deformed is small even with rectangular wire.

 

“More flexibility”

A Young's modulus approximating 40 GPa (i.e., super-low elastic modulus) and a tensile strength of approximately 1000 MPa (i.e., super-high strength). Compared to NiTi, GUMMETAL is more flexible, and its Young's modulus is approximately 85 GPa.

“Super-elastic”

GUMMETAL is super-elastic and has a ductility approximately 10 times (2.5%)
greater than that of conventional metals   

 

“True elastic deformation without hysteresis”

Unlike NiTi, super-elastic deformation in GUMMETAL is true elastic deformation without hysteresis (i.e., without energy loss between loading and unloading in the stress–strain relation). Its nonlinear elastic properties are not subject to the Hook's law

“Biocompatible and Non-toxic”

All constituent atomic elements of the alloy are biocompatible and non-toxic  

“No work-hardening”

Work-hardening does not occur during the forming process. Its super-elastic properties enable cold deformation up to 99.9% or higher without compensation (super-plastic deformation).


“Incomparable to other titanium wires”

Compared to other titanium wires, GUMMETAL wire generates approximately half the friction between the archwire and bracket with an appropriately treated surface
