Ni90Cr10 yog ib qho tsis muaj pakel-chromium alloy (nicr alloy (nicr alloy) rau kev siv thaum muaj 1200 ° C (2190 ° F). Lub alloy yog tus cwj pwm los ntawm kev ua siab tiv taus, zoo oxidation tsis kam thiab zoo ua kom ruaj khov. Nws muaj cov qauv ua tau zoo tom qab siv thiab zoo heev Veldability.
Ni90Cr10 yog siv rau hluav taws xob cua sov hauv cov khoom siv hauv tsev thiab muaj kev muaj cua sov. Cov kev siv tsis raug yog tiaj ua tiaj, ironing machine, tso dej sov, yas moulding Irons, hlau sheased tubular thiab cartridge ntsiab.
Vim yog cov nplaum nplaum zoo kawg nkaus ntawm cov oxide saum npoo av, ni90c10 muaj kev pabcuam zoo tshaj plaws piv rau kev sib tw Nickel-liclocs.

Chromel vs alumel yog siv nyob rau hauv oxidizing, inert lossis qhuav kom txo cov cua nab kuab. Raug rau lub tshuab nqus hluav taws xob rau lub sijhawm luv luv. Yuav tsum muaj kev tiv thaiv los ntawm sulfurous thiab marginal oxidizing cua. Txhim khu kev qha thiab raug thaum muaj kev kub siab.Chromel: Chromel yog ib qho alloy ntawm kwv yees 90% npib tsib xee thiab 10% chromium. Nws yog siv rau ntawm cov khoom siv ntawm cov zoo ntawm cov hom ESI EN thiab hom K Thermocouples, pab kiag li rau kev ntsuas ntsuas kub ntawm ob tus neeg sib txawv.
