Performance and Characteristics of Nitinol Alloy

(Performance and Characteristics of Nitinol Alloy)

What is Nitinol Alloy?

Nitinol is a shape memory alloy, which is a special alloy that can
automatically restore its plastic deformation to its original shape at a certain
temperature, and has good plasticity.

Its expansion rate is over 20%, its fatigue life is up to 1*10 to the 7th
power, its damping characteristics are 10 times higher than that of ordinary
springs, and its corrosion resistance is better than the best medical stainless
steel at present, so it can meet various engineering and It is an excellent
functional material for medical application requirements. In addition to its
unique shape memory function, memory alloy also has excellent characteristics
such as wear resistance, corrosion resistance, high damping and super
elasticity.

Special properties of Nitinol Alloy：

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 ß
titanium alloy wires. Regarding the load-displacement curves of these
orthodontic wires in tensile test and three-point bending test conditions. The
unloading curve platform of Nitinol is the lowest and the flattest, indicating
that it can provide the most durable and soft correction force.

Good shock absorption characteristics: The greater the vibration caused by
chewing and night molars to the arch wire, the greater the damage to the root
and periodontal tissue. Through the results of different arch wire attenuation
experiments, it is found that the vibration amplitude of stainless steel wire is
larger than that of super-elastic Ni-Ti wire. The initial vibration amplitude of
super-elastic Ni-Ti arch wire is only half of that of stainless steel wire. The
good vibration and shock absorption characteristics of arch wire are The health
of teeth is very important, and traditional arch wires, such as stainless steel
wires, tend to increase root resorption.
