Nickel Titanium Wire 0.03mm – Black Oxidized Superelastic Nitinol

Description

Ultra-Fine 0.03mm Nickel Titanium Wire – Black Oxidized for Precision and Performance

Harness the Power of Nickel Titanium for Micro-Scale Innovation

Looking for a wire that’s ultra-thin, yet ultra-strong? Our Black Oxidized Nickel Titanium Wire (also known as Nitinol) at 0.03mm offers unmatched mechanical intelligence. Thanks to its shape memory and superelasticity, this wire bends, flexes, and returns to its original form—again and again. Whether you’re creating intricate medical tools or micro-scale components, this material redefines what’s possible.

Moreover, the exceptional miniaturization it allows makes it ideal for modern engineering challenges. In short, it offers strength, reliability, and intelligence—at a near-invisible scale.

What Makes Nickel Titanium (Nitinol) So Special?

Nickel Titanium is an intelligent shape memory alloy, often referred to as “muscle metal.” When heated, it returns to its pre-set form after being deformed. Unlike conventional metal wires, it can endure repeated bending and stress without sustaining permanent changes.

Due to its superior elasticity and excellent fatigue resistance, nickel titanium is extensively applied across precision-driven and critical sectors.
Moreover, our production process relies exclusively on high-purity nickel and titanium, ensuring stable transformation temperatures and uniform mechanical properties. This guarantees that each length of wire performs reliably and consistently.

Enhanced with a Black Oxidized Surface Finish

To improve durability and functionality, our 0.03mm wire is treated with a black oxidized finish. This is not a coating—it’s a chemically grown layer directly bonded to the surface.Consequently, it provides excellent protection against corrosion while minimizing friction during use.

In addition, the coating enhances biocompatibility, a vital factor for medical devices and wearable technologies. Moreover, the dark coloration increases visibility, facilitating easier handling and inspection.It even slightly strengthens the wire surface.

Precision at the Micro Level: 0.03mm Diameter

At just 0.03mm, this wire is as fine as a strand of hair—yet it retains all the core benefits of nickel titanium. Achieving this level of precision requires expert processing and stringent quality control. Nevertheless, we guarantee tight diameter tolerances and consistent properties throughout.

This ultra-thin wire opens the door to applications where larger wires are not an option. As technology continues to shrink, our material keeps up with your demands.
