Description
Premium 0.04mm Nickel Titanium Wire with Black Oxide Finish — Ultra-Fine Nitinol Wire for Precision Applications
Discover the superior performance of our 0.04mm nickel titanium wire featuring a durable black oxide finish. Engineered for demanding applications requiring exceptional elasticity, precise shape memory, and reliable durability, this ultra-fine Nitinol wire excels where precision and resilience matter most.
Premium Nickel Titanium Alloy (Nitinol) Delivering Superior Performance
Constructed from premium nickel titanium alloy, often identified as Nitinol. This unique material delivers two remarkable properties:
-
Super elasticity — Bend this wire sharply. Crush it flat. Release pressure. Watch it instantly spring back to perfect shape. Every time.
-
Shape memory — Program its original form once. Later, just add heat. See it snap back to that exact preset shape. Count on this performance. Again and again.
Result? Our Nitinol wire laughs at repeated stress. It conquers brutal environments. Demanding applications demand this wire.
Durable Black Oxide Coating Enhances Corrosion Resistance and Appearance
The black oxide surface finish adds a smooth, uniform black layer that significantly increases corrosion resistance and reduces surface friction. This coating preserves the wire’s core mechanical properties, ensuring the nickel titanium wire retains its super elasticity and shape memory while offering a sleek, non-reflective, professional appearance.
Ultra-Fine 0.04mm Diameter for Precision Micro-Engineering
With an ultra-fine diameter of just 0.04mm, this Nitinol wire achieves exceptional flexibility without sacrificing strength. We guarantee precise diameter control and perfect roundness throughout its length, making it perfect for intricate micro-scale designs and tight spaces. Our production also covers other diameters to suit diverse technical requirements.
Versatile Applications Across Medical, Dental, Electronics, and More
