Ultra-Fine 0.05mm Black Nitinol Wire – SMA Metal Precision

Description

Unleash the Power of Ultra-Fine SMA Metal

Black Oxidized 0.05mm Shape Memory Nitinol Wire for Precision Applications

Discover a smarter material for the smallest innovations—our 0.05mm Nickel Titanium (Nitinol) Wire, crafted in a durable black oxidized finish. As an advanced SMA metal, it offers both shape memory and superelasticity, enabling engineers to solve complex design challenges at the micro scale.

Unlike ordinary metals, this shape memory wire can recover its original form when exposed to heat. Additionally, its superelastic properties allow it to bend, twist, and stretch beyond conventional limits—without permanent deformation. As a result, this nitinol wire is a perfect fit for next-generation technologies requiring resilience and intelligence in minimal space.

Enhanced Surface: Uniform Black Oxide Finish

Through a specialized oxidation process, we apply a black oxide coating that does more than just look sleek. First, it improves scratch resistance and enhances durability. Second, the matte black surface reduces glare, providing excellent visibility under microscopes. Finally, it ensures a consistent texture that makes handling and assembly easier—especially in cleanroom or surgical environments.

Precision That Measures Just 0.05mm

At only 0.05mm in diameter, this superelastic wire is thinner than a human hair. Despite its size, it maintains remarkable uniformity and tensile strength. Because we manufacture it with extreme precision, every spool delivers consistent performance throughout its entire length.
