Superelastic and high-temperature superelastic alloys are binary nickel-titanium alloys better known as shape memory or Nitinol alloys. This is the first of several data sheets that cover these materials; this data sheet covers materials with an austenite start temperature of 10 deg C (14 deg F). This datasheet provides information on composition, physical properties, and tensile properties. It also includes information on forming and machining. Filing Code: Ni-643.
