Nitinol Open Coil Springs, Variable Force Spring, .012" x .030", 7"/Tube, 016440551230130

Nitinol open coil springs are used in orthodontic treatment to create and maintain space between teeth, delivering a variable force that is gentle at low activation and increases as the spring is compressed. This spring measures .012" wire diameter by .030" inner diameter and is supplied in a 7-inch tube. The nickel-titanium (Nitinol) alloy provides superelastic, shape-memory properties for consistent force delivery over a wide range of activation.
