He nui nā pono o ka nickel titanium alloy. ʻO ka mea mua, he hopena hoʻomanaʻo kupaianaha kona, hiki iā ia ke hoʻi i kona ʻano kumu ma hope o ka deformation ma lalo o kekahi mau kūlana. ʻO ka lua, hōʻike ia i ka super - elasticity, e ʻae ana i nā deformations nui me ka ʻole o ka pōʻino mau. Loaʻa iā ia ka biocompatibility maikaʻi, kūpono ia no nā noi olakino. Eia kekahi, hāʻawi ia i ka pale corrosion maikaʻi loa a me ke kūpaʻa luhi.
