Precision Alloy Iron Nickel wire Invar/ Vacodil36/ Feni36 ya Magalasi Osindikiza
Invar/ Vakodil36/Feni36Waya Wosindikiza Galasi
Gulu: otsika coefficient of thermal expansion alloy
Ntchito: Invar imagwiritsidwa ntchito pomwe pakufunika kukhazikika kwapamwamba kwambiri, monga zida zolondola, mawotchi, zoyezera zowuluka, mafelemu a chigoba cha kanema wawayilesi, ma valve mu ma motor, ndi mawotchi a antimagnetic. Poyang'ana nthaka, pamene kukwera kwapamwamba (kwapamwamba-kulondola) koyenera kuchitidwa, ndodo zowongolera zomwe zimagwiritsidwa ntchito zimapangidwa ndi Invar, m'malo mwa matabwa, fiberglass, kapena zitsulo zina. Ma invar struts adagwiritsidwa ntchito m'mapistoni ena kuti achepetse kukula kwawo kwamafuta mkati mwa masilinda awo.
