Precision Alloy Hlau Nickel xaim Invar / Vacodil36 / Feni36 rau Sealing Iav
Invar/ Vacodil36/Feni36Hlau rau Sealing Iav
Kev faib tawm: cov coefficient qis ntawm thermal expansion alloy
Daim Ntawv Thov:Invarsiv rau qhov twg xav tau kev ruaj khov siab, xws li cov cuab yeej precision, moos, seismic creep gauges, TV shadow-mask frames, valves hauv motors, thiab antimagnetic watches. Hauv kev soj ntsuam av, thaum thawj-kev txiav txim siab (high-precision) elevation leveling yuav tsum tau ua, cov leveling rods siv yog ua los ntawm Invar, es tsis txhob ntoo, fiberglass, lossis lwm yam hlau. Invar struts tau siv rau hauv qee lub pistons los txwv lawv cov thermal expansion hauv lawv lub tog raj kheej.
Cov Tshuaj Muaj Peev Xwm hauv%, Invar

| P 0.015% | Mo 0.1% | V 0.1% | Al 0.1% | Cu 0.1% | Cr 0,15% |
Cov yam ntxwv tseem ceeb ntawm lub cev thiab cov khoom siv kho tshuab ntawm cov hlau nplaum:
Qhov Ceev: γ = 8,1 g / cm3;
Hluav taws xob tiv taus: ρ = 0,78 ohm mm2? / m;
Qhov kub ntawm Curie point: Θs = 230 ° C;
Modulus ntawm elasticity E = 144 kN / mm2;
Cov coefficient ntawm kev nthuav dav linear a1 (20-100 ºC) ≤1,5 * 10-6 ºC -1
