Super Invar 32-5

UNS #K93500

Super Invar 32-5 is a magnetic, austenitic, solid solution alloy containing iron, nickel and cobalt designed to provide minimum thermal expansion at room temperatures. This alloy also exhibits austenite stability to service temperatures at least -67°F (-55°C) and thermal expansion properties less than those of Invar 36 (36% nickel-iron) when used in the -67/203°F (-55/95°C) temperature range.
