G4™ Nickel Titanium Closed Coil Springs with Eyelets

The unique G4™ Nickel Titanium alloy developed by G&H® is precision formed into closed coil springs. G4™ Springs provide consistent force and remain active until the space is closed. Consistent force values and full recovery are both routinely achieved with G4™ NiTi Springs – and also G4™ NiTi Archwires.
