Isishwankathelo seMveliso

Intambo ye-alloy ye-4J33 yinto ye-alloy ye-Fe-Ni-Co echanekileyo nelula, eyenzelwe ngokukodwa ukusetyenziswa kwe-hermetic glass-to-metal sealing. Imalunga ne-33% nickel kunye nenani elincinci le-cobalt, le ngxubevange inika i-thermal expansion coefficient ehambelana kakhulu neglasi eqinileyo kunye ne-ceramics. Isetyenziswa kakhulu ekwenziweni kwee-vacuum tubes, ii-infrared sensors, ii-electronic relay, kunye nezinye izixhobo ezithembekileyo kakhulu.
