Abstract
Fabrication of metal medical instruments and devices from a shape memory alloy which provides greater flexibility in design and avoids the need for substantial cold working of the alloy which is required in other methods. The new process provides a ductile alloy for ease of forming and a unique heat treatment which renders the fabricated orthodontic and medical components highly elastic, with a high resistance to kinking and with good corrosion resistance. In addition, this new process produces orthodontic and medical components useful over the temperature range of from -20 to +40 degrees C.
