Invar® / Super Invar®

About Invar® and Super-Invar® Alloys

Invar® is made up of 64% dzelzs un 36% niķelis. Invar is known for its excellent properties of controlled coefficient of thermal expansion. Invar® end uses include glass sealing, pulksteņi, laboratorijas ierīces, šļūdes mērītāji, shadow-mask frames and valves in motors. Invar® (36% NI-Balance dzelzs) Alloy has been the high temp metal of choice for low expansion applications for years.

“Super-Invar®” (31% NI-5% līdzsvara līdzsvara dzelzs) ir atradis zināmu labvēlību, jo tam ir gandrīz nulle siltuma izplešanās koeficients ierobežotā temperatūras diapazonā. “Super Invar®” lietderīgais diapazons ir ierobežots no -32 ° līdz + 275° C. because the material begins to transform from Austenite to Martinsite at temperature below-32°F Invar and Super Invar® are iron-nickel alloys that are known and named for their resistance to thermal expansion. This steady, resistant shape in all temperatures makes them an ideal material for delicate measuring instruments, pulksteņi, watches, communication devices and other sensitive machines. Eagle Alloys supplies Invar® and Super Invar® rods, spoles, sheets and plates in various sizes and thicknesses to suit a wide array of applications.

Invar® alloy is also available in a second variation know as Free-Cut (FC) Invar 36® or Free-Machining (FM) (UNS K93050 per ASTM-F-1684). A small amount of selenium is added to enhance machinability for high productivity applications. Eagle Alloys supplies dozens of metals for machining, manufacturing and finishing thousands of products. All of our metals adhere to strict quality standards to ensure that your finished products, tools and equipment exceed your expectations. Top-quality parts, components and products begin with the best materials, especially when dealing with sensitive measuring instruments and delicate devices. We produce Invar and Super Invar according to your needs and specifications to build a product you can count on.
