Ni-Ti Alloy Wire (also known as Nitinol Wires) is an alloy with a nearly equiatomic composition (i.e. 49%-51%) of nickel and titanium. Ni-Ti belongs to the class of shape memory alloys that can be deformed at low temperature and recover their original and permanent shape when exposed to high temperatures. Nitinol, also known as nickel-titanium alloy or Ni-Ti, is widely used in orthodontics due to its shape memory and super-elastic behavior. We use archwires made from this clever metal alloy to efficiently move teeth and reduce the frequency of adjustments. In many cases it is replaced by Nitinol Alloy Wires in an application that has traditionally used stainless steel. In most cases, Nitinol is substituted to take advantage of its unique superelasticity or shape memory. Nitinol’s modulus is highly nonlinear and not as stiff as stainless steel.
We as Siddhgiri Tubes is a known exporter, manufacturer and stockist of Nitinol Wires, which exhibit two unique and closely related properties: shape memory effect and superelasticity (also called pseudoelasticity). Nitinol allergy is a rare phenomenon, with only a few cases reported. However, allergy to nickel, a predominant component of NiTi Wires, is much more common. Despite the prevalence of nickel allergy, few patients have clinical manifestations. Shape memory alloys are generally made by casting, using vacuum arc melting, or induction melting. These are special techniques used to keep impurities in the alloy to a minimum and ensure the metals mix well. The billet is then hot rolled into longer lengths and then drawn into wire.
