ASTM F2063

Nickel-Titanium Shape Memory Alloys for Medical Devices and Surgical Implants

ASTM F2063 is a standard specification for Wrought Nickel-Titanium Shape Memory Alloys for Medical Devices and Surgical Implants. It covers the chemical, physical, mechanical, and metallurgical requirements for wrought nickel-titanium bar, flat rolled products, and tubes containing nominally 54.5- to 57.0-weight percent nickel and used for the manufacture of medical devices and surgical implants.
