Weldable Low Thermal Expansion Coefficient Invar 36 Bar

 Low Thermal Expansion Coefficient Invar 36 Bar (Ni36Fe, Fe-36Ni, NiInvar)

Invar 36 is used where high dimensional stability is required,such as precision insturmrent,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.
