Product Description

Invar 36 Invar 42 Kovar bar Suppliers of Invar 36 / Nilo 36 / Alloy 36 K93600 / K93601

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

​Invar 36 Flat Bar magnetic at temperatures below its Curie point and non-magnetic at temperatures above. Invar 36 Polished Bar are standard alloy for low expansivity up to 400 °F.
