I-Precision Alloy Iron Nickel wire Invar/Vacodil36/ Feni36 ye-Sealing Glass
I-Invar/Vacodil36/Feni36Intambo Yengilazi Yokuvalwa
Ukwahlukaniswa : I-coefficient ephansi ye-thermal expansion alloy
Uhlelo lokusebenza: I-Invar isetshenziswa lapho kudingeka khona ukuzinza kwe-dimensional ephezulu, njengamathuluzi anembayo, amawashi, ama-gauge e-seismic creep, amafreyimu emaski kamabonakude, ama-valve kumamotho, namawashi e-antimagnetic. Ekuhloleni umhlaba, lapho ukulinganisa kokuphakama kwe-oda lokuqala (okunemba okuphezulu) kufanele kwenziwe, izinti zokulinganisa ezisetshenziswayo zenziwe nge-Invar, esikhundleni sokhuni, i-fiberglass, noma ezinye izinsimbi. Ama-Invar struts asetshenziswa kwamanye ama-piston ukukhawulela ukwanda kwawo okushisayo ngaphakathi kwamasilinda awo.

Izimo eziyisisekelo zomzimba kanye nezakhiwo zemishini ye-alloy:
Ukuminyana: γ = 8,1 g / cm3;
Ukumelana nogesi: ρ = 0,78 ohm mm2 ? m;
Izinga lokushisa lephoyinti leCurie: Θs = 230 ° C;
I-modulus ye-elasticity E = 144 kN / mm2;
Umugqa wokunweba i-coefficient a1 (20-100 ºC) ≤1,5 * 10-6 ºC -1
