Product Specification

Nitinol Wire Nickel Titanium Alloy Memory Wire

1. Specification Of Nitinol Wire:

Shape memory nitinol wire could be used to develop implants that can be inserted into the body in a compact shape and, once implanted, activate their functional form. If you need wire in a specific shape for a specific application, we offer shape sets. This sets a filament shape that is specific to your device design requirements. We not only produce various forms of nickel-titanium alloys, but also control the entire production process of nickel-titanium alloys from beginning to end. In the field of medical equipment, we provide the world's leading raw materials from nickel-titanium alloy melts to finished products.

Superelasticity occurs at temperatures just above the transition temperature, allowing the material to recover from strains of up to 8%, with permanent strains set at 0.5% or less.

Nitinol wire comes in two basic forms: Nitinol wire and flat wire, and Nitinol centerless ground rod.

Round wire:	dia 0.05mm ~ 4.0mm
Flat yarn aspect ratio:	W/T < 10
Strip aspect ratio:	W/T >10:1
Flat Wire Minimum thickness:	0.008mm
Flat Wire Maximum width:	11.5mm
Surface:	Light oxidation, dark oxidation, black oxidation, no oxidation
Standard:	ASTM F2063,ASTM F2633,ASTM F2005,
Other size and standard can custom according to customer requirement.

3.Chemical Content According to ASTM F2063:

4. Special Properties Of Nickel Titanium Alloy Memory Wire:

1.) Shape memory

2.) Super elasticity

3.) Sensitive to oral temperature changes

4.) Excellent corrosion resistance

5.) Anti-toxicity

6.) Gentle corrective power

7.) Good shock absorption characteristics

5. Surface Quality Of Nickel Titanium Alloy Wire:

1.) Light Oxidation - Diamond Drawn Surface

2.) Dark Oxidation - Diamond Drawn Surface

3.) Black Oxide - Diamond Drawn Surface

4.) Etching - chemically removes the oxide layer, leaving the surface smooth

5.) Pickling - chemically removes the oxide layer, plus a small amount of base metal, leaving a rough texture on the surface

6.) Etching and mechanical polishing - chemically remove the oxide layer and then mechanical polishing, the surface will have a stainless steel appearance (micro scratches will be found when magnifying 40x)

7.) Oxide-free - Smooth, no visible oxides

6. Nitinol Wire Application:

Nitinol wire is used in many different medical and industrial applications. Medical applications include vascular therapy, heart rhythm management, neurostimulation, orthodontics, orthopedics, endoscopy, dental implants, and more. Typical medical applications include guide wires, braided stents, root files, dental arch wires, IUDs, sutures, etc.

Some typical applications for each NiTi alloy medical grade are given below:

Nitinol A: Guide wires, brackets, needles, molding cores, stone removal baskets, orthodontic files, etc.

Nitinol B*: Often used in situations where higher plateau loading and unloading stresses at room temperature are required. The addition of chromium lowers the transformation temperature and increases the tensile strength.

Nitinol C**: Applications requiring increased stiffness. Cobalt doping lowers the transition temperature and increases tensile strength.

Nitinol D: Provides excellent cycling performance at body temperature (37°C).

Nitinol E: A common application for this alloy is in high temperature actuators.

Nitinol F: A common application for this alloy is in high temperature actuators.

Nitinol G: Typically used in applications requiring phase changes at body temperature (37°C).

Nitinol H: Suitable for extremely low temperature environments.
