Material Data Sheet

Super Invar 32-5 is a magnetic, austenitic,solid solution alloy containing 32% Nickel, 5% Cobalt, and a balance of Iron.It was designed to provide minimum thermal expansion at room temperatures (onehalf that of Invar Alloy)

A low coefficient of thermal expansion(CTE) is the most important characteristic of all Invar types and especiallyof Super Invar. The CTE of Super Invar is around one third the CTE ofregular Invar and is almost zero after specific heat processing.

This alloy also exhibits austenitestability to a service temperature of at least -67°F and thermal expansionproperties besting Invar alloys when used in the 67/203°F (-55/95°C)temperature range. The minimal expansion of Super Invar over this range oftemperatures makes this alloy useful in many applications including structuralcomponents and substrates in instrument systems requiring precisionmeasurements.
