Description:
Super Invar 32-5 Alloy Applications
Super Invar Alloy is a low expansion alloy that is designed to provide minimum thermal expansion at room temperatures, and thermal expansion properties less than those of Invar Alloy when used in the -67/203°F (-55/95°C) temperature range. While Invar Alloy compositions is 36% Nickel, and the remaining balance Iron, the composition of Super Invar Alloy is 32% Nickel, 5.5% Cobalt and the remaining balance Iron. Super Invar Alloy’s minimal expansion over this range of temperatures, makes this alloy useful in many applications including structural components and substrates in instrument systems requiring precision measurements. Some of the applications of Super Invar Alloy include:Optical instruments
Telescopes
Laser instruments and equipment
Ring laser gyroscopes
Laser benches
Positioning devices
Metrology devices
Scientific instruments
Structural components and supports for optical and laser systems
Applications that require lower expansivity than Invar.
