Precision Alloy Iron Nickel wire Invar/Vacodil36/ Feni36 yokutywina iglasi
Invar/ Vacodil36/Feni36Ucingo lokutywina iglasi
Ukwahlula : i-coefficient ephantsi ye-alloy yokwandisa i-thermal
Usetyenziso: I-Invar isetyenziswa apho uzinzo oluphezulu lwe-dimensional lufuneka, olufana nezixhobo ezichanekileyo, iiwotshi, iigeyiji ze-seismic creep, iifreyimu zesithunzi sesithunzi sikamabonakude, iivalvu kwiimoto, kunye newotshi ye-antimagnetic.Ekuhlolweni komhlaba, xa kufuneka kwenziwe i-oda lokuqala (lokuchaneka okuphezulu), iintonga zokulinganisa ezisetyenzisiweyo zenziwe nge-Invar, endaweni yomthi, i-fiberglass, okanye ezinye iintsimbi.I-Invar struts isetyenziswe kwezinye iipiston ukukhawulela ukwanda kwe-thermal ngaphakathi kweesilinda zazo.

Iziseko zomzimba ezisisiseko kunye neempawu zoomatshini zealloy:
Ubuninzi: γ = 8,1 g / cm3;
Ukuxhathisa kombane: ρ = 0,78 ohm mm2 ?/ m;
Ubushushu bendawo yeCurie: Θs = 230 ° C;
Imodyuli ye-elasticity E = 144 kN / mm2;
Ukwandiswa komlinganiso womgqa ngu-a1 (20-100 ºC) ≤1,5 * 10-6 ºC -1
