Several different metals are used in orthodontic appliances, and their physical properties and mechanical behavior are the very life blood of orthodontic therapy. Recent advances in orthodontics have resulted in a varied array of wires that exhibit a wide spectrum of properties. Up until the 1930’s the only orthodontics wires available were made of gold. Austenitic stainless steel with its greater strength, higher modulus of elasticity, good resistance to corrosion, moderate costs was introduced as an
