Material: Nitinol Metal Wo with Super Properties

Our metal wo is crafted from a precisely engineered Nickel-Titanium alloy known as Nitinol. It offers two exceptional properties: Shape Memory, enabling the wire to revert to its original shape when exposed to heat, and Superelasticity, allowing extreme flexibility without permanent distortion. These features provide outstanding fatigue resistance, high stress tolerance, and dependable performance even at micro-scale levels.

Black Oxide Finish: Protection & Precision

We apply a specialized black oxide treatment to enhance corrosion resistance, reduce nickel release, and improve surface hardness. This matte black layer not only boosts durability but also makes the wire easier to handle under magnification—an essential advantage in medical and micro-device assembly.

Extreme Accuracy at 0.04mm Diameter

This metal wo wire delivers incredibly tight dimensional tolerance—just 0.04mm in diameter, thinner than a strand of hair. Our advanced manufacturing ensures consistent thickness along every spool. Its slim profile allows for unprecedented design freedom in the tiniest mechanical, electrical, and medical systems.
