Nitinol strip and foil (rolled from flat wire, Superelastic, and shape memory), ASTM F2063 (Chemistry)

Edgetech Industries LLC offers Nitinol foil (titanium nickel alloy foil) with 0.002″ thinnest thickness.Our continuous-length nitinol foil is available in fully annealed or super-elastic conditions, which works well in stamping, forming, and other secondary operations. Our foil is manufactured to meet rigorous alloy composition, mechanical, and dimensional specifications. A special process for nitinol foil with <0.08mm thick will be needed.

Nitinol is known for its thermomechanical properties of superelasticity and shape memory effect. Shape memory refers to the ability of nickel-titanium alloys to deform at a certain temperature and then return to their original formed shape when heated above their transformation temperature. Superelasticity occurs in a narrow temperature range slightly above its transformation temperature; in this case, no heating is required to restore the formed shape, and the material exhibits enormous elasticity, about 10-30 times that of ordinary metals.
