4J36 (Invar) imagwiritsidwa ntchito pamene pakufunika kukhazikika kwapamwamba, monga zida zolondola, mawotchi, ma geji oyendera chivomerezi, mafelemu a chigoba cha wailesi yakanema, ma valve mu ma mota, ndi mawotchi oletsa maginito. Pofufuza malo, pamene kuyeza kwapamwamba (kolondola kwambiri) kuyenera kuchitika, ndodo ya Level (ndodo yoyezera) yomwe imagwiritsidwa ntchito imapangidwa ndiInvar, m'malo mwa matabwa, fiberglass, kapena zitsulo zina. Ma strut a Invar ankagwiritsidwa ntchito m'ma pistoni ena kuti achepetse kutentha kwawo mkati mwa masilinda awo.

4J36 imagwiritsa ntchito oxyacetylene welding, magetsi a arc welding, welding ndi njira zina zowotcherera. Popeza kuchuluka kwa kukula ndi kapangidwe ka mankhwala a alloy kuyenera kupewedwa chifukwa kuwotcherera kumayambitsa kusintha kwa kapangidwe ka alloy, ndibwino kugwiritsa ntchito zitsulo zodzaza za Argon arc welding welding makamaka zomwe zili ndi 0.5% mpaka 1.5% titanium, kuti muchepetse porosity ya weld ndi ming'alu.
