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 excellent wear resistance and corrosion resistance characteristics, as well as super-elasticity, high damping capacity, and wear resistance.
What is Nitinol Performance?
As its name implies, Nickel-Titanium Alloy Powder is a binary alloy powder that is composed 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 is parent phase – R phase – martensite. The R phase has a rhombohedral shape, while the austenite cubes become hard and brittle when temperatures are high or when a load is removed. The shape of the material is relatively stable. The martensite is the state of the metal at relatively low temperatures, or under loads. It is hexagonal, repeatable and unstable.
What are the special properties of Nitinol?
Shape memory: Shape memory is formed 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 unique chemical makeup, that is it is an alloy atomic such as Nitinol containing around 50% nickel. Nickel is well known for its carcinogenic, cancer-promoting properties.
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-absorbing characteristics: The more vibrations of the archwire due to chewing or night molars there are, the more damage the roots and periodontal tissues suffer.
