Precision alloys emphasize special physical properties. The main international grades include: Invar 36 (UNS K93603, extremely low coefficient of thermal expansion, used in LNG storage tanks and precision instruments), Kovar (UNS K94610, glass-metal sealing alloy), Alloy 42 (UNS K94100, semiconductor lead frame), Permalloy (such as UNS N14080 / N14076 series, high permeability soft magnetic alloy, used for magnetic shielding and magnetic heads), and Elinvar type (such as Ni-Span C) used for constant elastic hairsprings.
