Ukuhlukaniswa: i-coefficient ephansi ye-alloy yokwandisa ukushisa

Ukusetshenziswa: I-Invar isetshenziswa lapho kudingeka khona ukuzinza okuphezulu, njengezinsimbi zokunemba, amawashi, ukuzulazula kokuzamazama komhlaba
amageyiji, ozimele be-shadow-mask kamabonakude, ama-valve kuma-motor, kanye namawashi alwa nomagnetic. Ekuhloleni umhlaba, lapho kuqala uku-oda
(ngokunemba okuphezulu) ukulinganisa ukuphakama kuzokwenziwa, izinduku zokulinganisa ezisetshenziswayo zenziwe nge-Invar, esikhundleni sokhuni, i-fiberglass, noma
ezinye izinsimbi. Ama-Invar strut asetshenziswa kwamanye ama-piston ukuze anciphise ukwanda kwawo kokushisa ngaphakathi kwamasilinda awo.
