Product Description

4J29 ( Kovar ) 4J32 4J33 4J34 4J36(Invar ) 4J50 Strip Nickel Alloy for Heating

 
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.
