Nitinol
It is made of shape memory alloy. This is a special metal alloy that, at a given temperature, can return to its original plastic shape.
Memory alloys have many other excellent qualities, such as corrosion resistance, high damping or super-elasticity, in addition to their unique memory function.
What is Nitinol Performance?
As its name implies, nickel-titanium powder is a binary metal powder that consists of both nickel and titanium. The austenite phase, and the martensite phases are different due to changes in temperature or mechanical pressure. The order of phase transformation during nickel-titanium alloys cooling is parent-R-martensite. The R phase has a rhombohedral shape, while the austenite cubes become hard and brittle when temperatures are high or the load is removed. The shape of the material is stable. The martensite is the state of a material at relatively low temperatures, or when it’s under stress. It is ductile and repeatable. It’s also unstable and easily bent.
What are the special properties of Nitinol?
Shape memory: Shape memory occurs when a parent phase is cooled to below Mf from above Af. This martensite phase is then deformed and heated back to Af. The material will automatically revert to its parent phase.
Superelasticity: The term superelasticity describes the phenomenon in which a sample is strained beyond its elastic limit strain when subjected to external forces, but the strain automatically returns after the force has been removed.
Sensitivity of orthodontic wires to temperature changes: The orthodontic power and strength of CoCr orthopedic wires is not significantly affected by temperature.
Corrosion resistance According to recent studies, the corrosion resistance between stainless steel and nickel-titanium is almost identical.
Anti-toxicity: Nitinol has a special composition. This is because it is an alloy atomic, such as Nitinol. Nickel contains approximately 50% and has been known to promote cancer.
Gentle orthodontic power currently commercially used orthopedic wires include austenitic stainless steel wires, cobalt-chromium-nickel alloy wires, nickel-chromium alloy wires, Australian alloy wires, gold alloy wires and nickel-titanium alloy wires.
Good shock absorption: The more the archwire vibrates from chewing or night molars the more damage is done to the periodontal and root tissue.
