Nickel Titanium Nitinol Wire – 3mm Bright Oxidized | Discover What Nitinol Is Used For
Meet our advanced material solution: Nickel Titanium (Nitinol) Wire, 3mm Diameter, Bright Oxidized State. This is not just wire—it’s smart wire. Engineered to remember its shape and spring back into form, this wire offers shape memory and superelasticity, solving complex design and engineering challenges across industries.
Premium Alloy: The Power Behind the Performance
Crafted from high-purity Nickel Titanium alloy, this wire features an approximately 1:1 nickel-to-titanium ratio. This balance enables the unique phase transformation behaviors that define Nitinol. Thanks to our precise manufacturing processes, every batch performs with consistent transformation temperatures and mechanical properties.
Surface Excellence: Bright Oxidized State
Our Nitinol wire features a Bright Oxidized finish—a smooth, metallic-grey surface created during heat treatment. This thin oxide layer isn’t just for looks. It adds light corrosion resistance, reduces surface friction, and enhances durability during handling. The result? A wire that’s clean, resilient, and ready for your application.
Engineered Dimensions: Perfect 3mm Diameter
Sized to 3mm (0.118 inches), this wire balances strength and flexibility.It delivers strong actuation capabilities without sacrificing flexibility.Our quality control ensures consistent roundness and tolerance, making this dimension ideal for actuators, springs, and structural applications.
What Is Nitinol Used For? Smart Solutions Across Industries
Thanks to its unmatched mechanical behavior, our 3mm bright oxidized Nitinol wire excels in various cutting-edge applications:
Medical Applications
-
Surgical Instruments: The wire flexes easily for insertion but returns precisely to shape inside the body—ideal for guidewires, retrieval devices, or biopsy forceps.
-
Orthodontics: Nitinol archwires apply gentle, consistent pressure, requiring fewer adjustments and increasing patient comfort.
-
Bone Fixation: Shape memory allows implants such as staples or bone clamps to activate at body temperature, securing fractures with minimal invasiveness.
Industrial & Mechanical Innovation
