    FeNi Nickel Iron alloy mwatsatanetsatane 0.5mmInvar 36 Wayakwa Kusindikiza Chida Cholondola

     

    INVAR 36ndi nickel-iron, aloyi yowonjezera yotsika yokhala ndi 36% nickel. Imasunga Miyeso yokhazikika Pamitundu yosiyanasiyana ya kutentha kwa mlengalenga, ndipo imakhala ndi coefficient yotsika yowonjezera kuchokera ku kutentha kwa cryogenic kufika pafupifupi 500 ° F. Alloy imakhalanso ndi mphamvu zabwino komanso zolimba pa kutentha kwa cryogenic.

    INVAR 36ikhoza kukhala yotentha komanso yozizira kupangidwa ndikupangidwa ndi makina pogwiritsa ntchito njira zofanana ndi

    zitsulo zosapanga dzimbiri za austenitic. INVAR 36 imatha kuwotcherera pogwiritsa ntchito Filler Metal CF36 yomwe ili

    kupezeka muwaya wopanda kanthu panjira zonse za GTAW ndi GMAW.
