6 reasons that nitinol considered to be ideal material for medical use
1. good shape memory effect:When the temperature rises to the body temperature, the material will automatically return to its original shape, so it is an ideal human implant material
2. Super elasticity: elastic modulus is 8 times that of stainless steel
3. The nitinol alloy material does not contain cadmium, mercury or hexavalent chromium. this material can be used medically in the human body, such as the heart stent.
4. It is light material: the density is around 6.5g/cm3
5. Very good corrosion resistance,and with longer service life.
6. Good biocompatibility: Nitinol alloy forms a stable passivation film with organisms.
