Precision Alloy Iron Nickel waya Invar/ Vacodil36/ Feni36 yeKuvharisa Girazi
Invar/ Vacodil36/Feni36Waya Yekuvhara Girazi
Classification: yakaderera coefficient ye thermal kuwedzera alloy
Chishandiso: Invar inoshandiswa panodiwa kugadzikana kwepamusoro-soro, senge zviridzwa, wachi, seismic creep gauges, terevhizheni shadow-mask mafuremu, mavharuvhu mumamotor, uye antimagnetic wachi. Mukuongorora ivhu, kana yekutanga-yakarongeka (yakakwirira-chaiyo) kukwirisa kukwirisa kunofanirwa kuitwa, matanda ekuyera anoshandiswa anogadzirwa neInvar, pachinzvimbo chehuni, fiberglass, kana mamwe simbi. Invar struts yakashandiswa mune mamwe mapistoni kudzikamisa kuwedzera kwemafuta mukati memasilinda avo.
