Invar 36 nickel-ferrum est, humilis dilatatio mixturae quae 36% nickel continet, ac rate expansionis scelestae circiter decimam partem ferri carbonii possidet. Admisce 36 fere constantes dimensiones in temperaturis atmosphaerici normalibus conservat, et humilem expansionis coefficientem ab temperaturis cryogenicis usque ad 500°F. Hoc nickel mixtura ferri obdurat, versatile et bonum robur in temperaturis cryogenicis retinet.

Invar 36 ponitur maxime pro;

• Aircrafts controls
• Systemata optica & laser
• Radio & electronic cogitationes
• Composita instrumenta formandi & dies
• Cryogenic components
