Tšepe e nang le tšepe e nang le tšepe ea nikeli, terata ea Invar/ Vacodil36/ Feni36 bakeng sa khalase e koalang
Invar/ Vacodil36/Feni36Terata ea Khalase ea ho Tiisa
Tlhophiso: coefficient e tlase ea motsoako oa katoloso ea mocheso
Kopo:Invare sebediswa moo ho hlokahalang botsitso bo boholo, jwalo ka disebediswa tse nepahetseng, dioache, di-geuge tsa ho thothomela ha lefatshe, diforeimi tsa maske ya moriti wa thelevishene, di-valve tse dienjini, le dioache tse thibelang makenete. Ha ho hlahlojwa naha, ha ho lokela ho etswa ho lekanyetsa bophahamo ba pele (ho nepahala ho hoholo), dithupa tsa ho lekanyetsa tse sebediswang di entswe ka Invar, ho ena le lehong, fiberglass, kapa ditshipi tse ding. Di-strut tsa Invar di ne di sebediswa dipistonng tse ding ho fokotsa katoloso ya tsona ya mocheso ka hara disilindara tsa tsona.
