Uns K93600 Invar 36 Ribbon Daidaitaccen Faɗawar Alloy Flat Waya
Farashin K93600 Invar36 Ribbon Madaidaicin Fadada Alloy Flat Waya
(Na kowa Suna:Invar, FeNi36, Invar Standard, Vacodil36)
4J36Invar), wanda kuma aka fi sani da suna FeNi36 (64FeNi a cikin Amurka), wani nau'in nickel-iron sananne ne don ƙarancin ƙarancin haɓakar haɓakar thermal (CTE ko α).
Ana amfani da 4J36 (Invar) inda ake buƙatar kwanciyar hankali mai girma, kamar kayan aiki daidai, agogo, ma'aunin girgizar ƙasa, firam ɗin-mask inuwar talabijin, bawuloli a cikin injina, da agogon antimagnetic. A cikin binciken ƙasa, lokacin da za a yi matakin farko (madaidaici) matakin haɓaka, ma'aikatan Level (sanda mai daidaitawa) da ake amfani da su ana yin su ne da Invar, maimakon itace, fiberglass, ko wasu karafa. An yi amfani da invar struts a wasu pistons don iyakance haɓakar zafi a cikin silindansu.
4J36 amfani da oxyacetylene waldi, lantarki arc waldi, walda da sauran hanyoyin walda. Tun da coefficient na fadadawa da sinadaran abun da ke ciki na gami ya kamata a kauce masa saboda walda yana haifar da canji a cikin abun da ke ciki, yana da kyau a yi amfani da Argon arc waldi walda filler karafa zai fi dacewa ya ƙunshi 0.5% zuwa 1.5% titanium, domin rage walda porosity da fasa.
