Uns K93600 Invar36 Ribhoni Precision Ukwandiswa kweAlloy Wire Flat
(Igama Eliqhelekileyo:Invar, FeNi36, Invar Standard, Vacodil36)
4J36 (Invar), eyaziwa ngokubanzi njenge-FeNi36 (i-64FeNi e-US), i-alloy ye-nickel-iron ephawulekayo ngenxa ye-coefficient ephantsi yokwandiswa kwe-thermal (CTE okanye α).
I-4J36 (I-Invar) isetyenziswa apho uzinzo oluphezulu olufunekayo, olufana nezixhobo ezichanekileyo, iiwotshi, iigeyiji ze-seismic creep, iifreyimu zesithunzi sesithunzi sikamabonakude, iivalvu kwiimotor, kunye newotshi ye-antimagnetic. Ekuhlolweni komhlaba, xa i-oda yokuqala (i-high-precision) yokunyusa umgangatho kufuneka yenziwe, abasebenzi beNqanaba (intonga yokulinganisa) esetyenzisiweyo yenziwe nge-Invar, endaweni yomthi, i-fiberglass, okanye ezinye izinyithi. I-Invar struts isetyenziswe kwezinye iipiston ukukhawulela ukwanda kwe-thermal ngaphakathi kweesilinda zazo.
I-4J36 isebenzisa i-oxyacetylene welding, i-arc ye-arc yombane, i-welding kunye nezinye iindlela ze-welding. Ekubeni i-coefficient yokwandisa kunye nokwakheka kweekhemikhali ze-alloy inxulumene kufuneka igwenywe ngenxa ye-welding ebangela utshintsho kwi-alloy composition, kungcono ukusebenzisa i-Argon arc welding filler metals ekhethwayo iqulethe i-0.5% ukuya kwi-1.5% titanium, ukwenzela ukuba ukunciphisa i-weld porosity kunye nokuqhekeka.
