Invar/ Vacodil36/Feni36Silig loogu talagalay dhalooyinka lagu xidho
Kala-soocidda: isku-dhafan hooseeya ee daawaha fidinta kulaylka
Codsiga: Invar waxa loo isticmaalaa halka loo baahan yahay xasilloonida cabbir sare, sida qalabyada saxda ah, saacadaha, cabbiraha dhulgariirka, fareemada hadh-maskeedka telefishinka, matoorada matoorada, iyo saacadaha antimagnetic. Sahanka dhulka, marka heerka koowaad (sax-sare) la rabo in la sameeyo heerka sareynta, ulaha siman ee la isticmaalo waxay ka samaysan yihiin Invar, halkii ay ka ahaan lahaayeen alwaax, fiberglass, ama biro kale. Invar struts ayaa loo adeegsaday qaar ka mid ah pistons si loo xaddido fidinta kulaylka ee gudaha dhululubadahooda.
