Precision Alloy Iron Nickel wire Invar/ Vacodil36/ Feni36 bakeng sa ho Tiisa Khalase
Invar/ Vacodil36/Feni36Mohala bakeng sa Khalase ea ho Koala
Classification : coefficient e tlase ea alloy ea ho atolosa mocheso
Ts'ebeliso: Invar e sebelisoa moo ho hlokahalang botsitso ba maemo a holimo, joalo ka lisebelisoa tse nepahetseng, lioache, litekanyo tsa sesmic creep gauge, liforeimi tsa mask a moriti oa thelevishene, li-valve tsa lienjineri, le lioache tse thibelang makenete. Ha ho etsoa tlhahlobo ea mobu, ha ho etsoa boemo ba boemo bo phahameng ka ho fetisisa (ho nepahala ha boemo bo holimo), ho sebelisoa lithupa tsa ho lekanya li entsoe ka Invar, ho e-na le lehong, fiberglass kapa litšepe tse ling. Li-invar struts li ne li sebelisoa lipiston tse ling ho fokotsa katoloso ea tsona ea mocheso ka har'a lisilindara tsa tsona.
