Global Super Invar 32-5 Supplier
Super Invar 32-5 is a magnetic, austenitic, solid solution alloy with a low coefficient of thermal expansion (CTE). The CTE of Super Invar is around one third the CTE of regular Invar and is almost zero after specific heat processing.
Super Invar is Available in many forms we can offer a bespoke solution that meets your exact requirements and specification for your 32-5 application, be it from Plate, Bar, Sheet,
With over 20 years’ experience, our team has a combined wealth of knowledge about Super Invar and its different characteristics, so we can guarantee you will find the product that fits your requirements.

About Super Invar
Super Invar®, also known as Invar 32-5 and Alloy 32-5 is an austenitic, solid solution alloy that belongs to the low expansion alloys family.
The low coefficient of thermal expansion (CTE) is the most important characteristic of all invar types and especially of Super Invar®. The CTE of Super Invar® is around one third of the CTE of regular invar and is almost zero after specific heat processing.
Super Invar 32-5 was designed to provide minimum thermal expansion at room temperatures (one half that of Invar Alloy). This alloy also exhibits austenite stability to a service temperature of at least -67°F and thermal expansion properties besting Invar alloys when used in the 67/203°F (-55/95°C) temperature range. The minimal expansion of Super Invar over this range of temperatures, makes this alloy useful in many applications including structural components and substrates in instrument systems requiring precision measurements.
