  • Austenitic stainless steel, with its greater strength, higher modules of elasticity, good resistance to corrosion and moderate cost, was introduced as an orthodontic wire in 1929 and shortly afterwards gained popularity over gold.
  • Since then several other alloys with desirable properties have been adopted in orthodontics. These include cobalt-chromium, nickel titanium, beta-titanium, and multi-stranded stainless steel wires.
