  • Method for forming nickel/titanium braided arch wires
    Patent number: 5080584
    Abstract: An orthodontic arch wire exhibiting relatively constant force over range of deflection of 0.8-1.8 mm and resiliently returnable to its initial position from flexure up to 90.degree. is formed from a braid of nickel/titanium alloy. In the process for making the arch wire, eight strands of the alloy are initially formed into a braid of circular cross section which is then deformed into a rectangular cross section. The deformed braid is wound about a fixture, is heated treated on the fixture and thereafter cut to produce a pair of arch wires from each coil about the fixture. The nickel/titanium alloy is one having a nominal composition of 55% nickel and 45% titanium.
