Nitinol Grade 5 Wire Manufacturer and Supplier in India

HOME → Materials → Nitinol → Nitinol Grade 5 Wire

The Nitinol grade family (Grades 1-9) of Nickel-Titanium (NiTi) shape-memory alloy wire from the Fort Wayne Metals family has been developed with an austenite finish transformation temperature high enough for use as a thermal actuator, which is a component that remains inactive at room or body temperature but changes shape when the temperature goes above a specified point. This is in contrast to more commonly referred to Nitinol #1 (general medical/guidewire) and superelastic, room-temperature grades. Grade 5 is not a chemistry exception and meets or exceeds ASTM F2063 purity requirements, except for Grades 2 and 3, which are chromium- and cobalt-doped, respectively. Sachin Steel is the manufacturer and supplier of Nitro Grade 5 wire and other grade wires in different parts of the world.
