Nitinol Grade 1 Rod & Bar Manufacturer and Supplier in India

Q: What is Nitinol Grade 1?

Nitinol Grade 1 is a designation associated with NiTi #1, a superelastic Nitinol grade used for applications requiring elastic recovery around room and body temperature. Typical applications include guidewires, stents, stylets, forming mandrels, stone retrieval baskets, and orthodontic files.

Q: Is Grade 1 a universal Nitinol standard?

No. Grade 1 is part of a specific Nitinol numbering system and should not be treated as a universal ASTM grade designation. ASTM F2063 defines requirements for wrought nickel titanium material, while NiTi #1 identifies a specific superelastic grade in the Fort Wayne Metals classification.

Q: What is the difference between Nitinol Grade 1 and Grade 5?

Nitinol Grade 1 is associated with superelastic behaviour around room and body temperature. Grade 5 is associated with shape memory behaviour at higher transformation temperatures. The correct choice depends on whether the component needs immediate elastic recovery or temperature-activated shape recovery.

Q: What sizes are available for Nitinol Grade 1 Rod/Bar?

ASTM F2063 currently covers mill products from 5.50 to 94.0 mm in diameter or thickness. Actual commercial availability depends on the required diameter, length, surface finish, tolerance and material condition.

Q: Is Nitinol Grade 1 suitable for medical applications?

NiTi #1 is commonly used in medical applications that require superelastic behaviour, including guidewires, stents, stylets, stone retrieval baskets and orthodontic files. Material intended for a particular medical device should be specified and qualified according to the applicable device requirements and material standard.

Q: What is the transformation temperature of Grade 1 Nitinol?

Published NiTi #1 reference data gives an active Af range of approximately 10 to 18 °C. The actual transformation temperature of the supplied material depends on composition and processing and should be confirmed by the applicable test method and material documentation.

Nitinol Grade 1 Rod/Bar is a superelastic nickel-titanium material designed for applications that need high flexibility, elastic recovery, and reliable performance around room and body temperature. The material is commonly identified as NiTi #1 and is used for guidewires, stents, stylets, forming mandrels, stone retrieval baskets and orthodontic files. In rod and bar form, Nitinol provides a solid feedstock for machining, forming and precision component production where conventional metals may not provide the same level of recoverable strain.

Sachin Steel Centre supplies Nitinol products for medical, engineering and other high-performance applications, with material available to required dimensions and specifications.

Specification of Nitinol Grade 1 Rod/Bar

ASTM F2063 is the principal material specification referenced for wrought nickel titanium products used in medical device and surgical implant applications. The current ASTM specification covers bar and flat rolled products with nominally 54.5 to 57.0 per cent nickel. It also states that bar and plate can be supplied in hot-finished or cold-finished conditions followed by annealing or heat treatment.
