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.
