Invar36 FeNi36 Precision Alloy Capillary Pipe Used in Medicine Industry

OhmAlloy-4J36 (Expansion alloy)

(Common Name: Invar, FeNi36, Invar Standard, Vacodil36)

OhmAlloy-4J36 (Invar), also known generically as FeNi36 (64FeNi in the US), is a nickel–iron alloy notable for its uniquely low coefficient of thermal expansion (CTE or α).

OhmAlloy-4J36 (Invar) is used where high dimensional stability is required, such as precision instruments, clocks, seismic creep gauges, television shadow-mask frames, valves in motors, and antimagnetic watches. In land surveying, when first-order (high-precision) elevation leveling is to be performed, the Level staff (leveling rod) used is made of Invar, instead of wood, fiberglass, or other metals. Invar struts were used in some pistons to limit their thermal expansion inside their cylinders.
