Product Overview
Introduction to Nitinol Nickel-Titanium Alloy
MOKSH TUBES & FITTINGS LLP is a leading manufacturer, exporter, importer, stockist, and supplier of Nitinol products in a variety of forms including wires, rods, sheets, tubes, springs, strips, and customized components. Nitinol (Nickel Titanium Naval Ordnance Laboratory) is a unique metal alloy primarily composed of nickel and titanium, widely known for its two remarkable properties: Shape Memory Effect (SME) and Superelasticity.
Nitinol's ability to return to a predetermined shape when heated and its exceptional elasticity under stress make it an ideal material for a variety of medical, industrial, and aerospace applications. It also offers excellent corrosion resistance, biocompatibility, and fatigue resistance, especially under cyclic loading environments.
