D55.9% Nitinol Memory Wire with Black Oxidized Finish – Reliable Shape Memory & Enhanced Durability
Material Composition and Performance
Our D55.9% nitinol memory wire is crafted from premium nickel-titanium alloy, with 55.9% nickel balanced by titanium. This precise alloy composition ensures exceptional shape memory properties and superior superelasticity. Advanced heat treatment optimizes transformation temperatures, delivering consistent, reliable performance batch after batch.
Durable Black Oxide Surface Finish
Our tough black oxide coating battles corrosion. It slows wear dramatically. This finish creates a smooth, uniform surface. It cuts glare effectively. The wire survives tough settings easily. This protection boosts durability strongly. Your demanding applications gain lasting performance.
Precise Diameter Range & Customization
Available in diameters from 0.05 mm (0.002 inches) up to 2.0 mm (0.08 inches), our nitinol memory wire meets strict tolerance requirements. We accommodate custom size requests to suit micro-medical devices or larger industrial parts, ensuring every spool adheres to exacting specifications.
Versatile Applications of Nitinol Memory Wire
