High-modulus superelastic alloy wire for medical and dental purposes

A wire used for one of medical or orthodontia purposes, comprising an elongated, flexible metal wire core at least partially formed of a trinary alloy, the trinary alloy consisting of Nickel, Titanium, and Cobalt, the trinary alloy formed principally of the Nickel and the Titanium with lesser additive of Cobalt, whereby the trinary alloy has greater column strength and stiffness than binary Nitinol alloy of substantially similar diameter of the wire core, and the alloy having greater extension flexibility than 304 stainless steel alloy of substantially similar diameter of the wire core, wherein extent by which the trinary alloy has greater column strength and stiffness than the binary Nitinol alloy and extent by which the trinary alloy has greater extension flexibility than the 304 stainless steel alloy are variable based on variance of weight components of the Nickel, the Titanium, and the Cobalt of the trinary alloy, wherein weight percentages of the Nickel and the Titanium are reater than 40% and the weight percentage of the Cobalt is less than or equal to 2%.

A wire used for one of medical or orthodontia purposes, comprising an elongated, flexible metal wire core at least partially formed of a trinary alloy, the trinary alloy consisting of Nickel, Titanium, and Cobalt, the trinary alloy formed principally of the Nickel and the Titanium with lesser additive of Cobalt, whereby the trinary alloy exhibits a combination of column strength and kink resistance properties falling between same properties of 304 stainless steel alloy of substantially similar diameter of the wire core and of binary Nitinol alloy of substantially similar diameter of the wire core, wherein extent by which the trinary alloy has column strength and kink resistance properties falling closer to same properties of either the 304 stainless steel alloy or the binary Nitinol alloy are variable based on variance of weight components of the Nickel, the Titanium, and the Cobalt of the trinary alloy, wherein weight percentages of the Nickel and the Titanium are greater than 40% and the weight percentage of the Cobalt is less than or equal to to 2%.

A solid wire used for one of medical or orthodontia purposes, comprising an elongated, flexible metal solid wire core solely formed of a trinary alloy, the trinary alloy consisting of Nickel, Titanium, and Cobalt, the trinary alloy formed principally of the Nickel and the Titanium with lesser additive of Cobalt, whereby the trinary alloy has both an upper plateau (UP) and a lower plateau (LP) from a 3-point bend test that are respectively greater than a UP and a LP from same 3-point bend test of binary Nitinol alloy with substantially similar diameter as the solid wire core, wherein extent by which the upper plateau (UP) and the lower plateau (LP) of the trinary alloy is greater than the upper plateau (UP) and the lower plateau (LP) of the binary Nitinol alloy is variable based on variance of weight components of the Nickel, the Titanium, and the Cobalt of the trinary alloy present in the wire core, and wherein weight percentages of the Nickel and the Titanium are greater than 40% and the weight percentage of the Cobalt is less than or equal to 2%.
