I-Precision Alloy Iron Nickel wire yeSealing Glass
Udidi: i-coefficient ephantsi ye-alloy yokwandisa ubushushu
Ukusetyenziswa: I-Invar isetyenziswa apho kufuneka uzinzo oluphezulu, njengezixhobo zokuchaneka, iiwotshi, ii-seismic creep gauges, iifreyimu ze-TV shadow-mask, ii-valve kwiimoto, kunye neewotshi ezichasene nemagnethi. Ekuhlolweni komhlaba, xa kufuneka kwenziwe i-first-order (high-precision) elevation leveling level, iintonga zokulinganisa ezisetyenziswayo zenziwe nge-Invar, endaweni yomthi, i-fiberglass, okanye ezinye izinyithi. Ii-Invar struts zazisetyenziswa kwezinye ii-piston ukunciphisa ukwanda kwazo kobushushu ngaphakathi kweesilinda zazo.
