Invar/ Vacodil36/Feni36Terata ea Khalase ea ho Tiisa
Tlhophiso: coefficient e tlase ea motsoako oa katoloso ea mocheso
Tšebeliso: Invar e sebelisoa moo ho hlokahalang botsitso bo boholo, joalo ka lisebelisoa tse nepahetseng, lioache, li-gauge tsa ho thothomela ha lefatše, liforeimi tsa maske ea moriti oa thelevishene, li-valve tse lienjeneng, le lioache tse loantšang makenete. Ha ho etsoa lipatlisiso tsa mobu, ha ho etsoa ho leka-lekanya bophahamo ba odara ea pele (e nepahetseng haholo), lithupa tsa ho leka-lekanya tse sebelisoang li entsoe ka Invar, ho e-na le lehong, fiberglass, kapa litšepe tse ling. Li-strut tsa Invar li ne li sebelisoa lipiston tse ling ho fokotsa katoloso ea tsona ea mocheso ka har'a lisilindara tsa tsona.
