PRODUCT DESCRIPTION
Invar 36 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.
