ʻO Ni90Cr10 kahi austenitic nickel-chromium alloy (NiCr alloy) no ka hoʻohana ʻana i nā mahana a hiki i 1200°C (2190°F). Hōʻike ʻia ka alloy e ka resistivity kiʻekiʻe, ke kūpaʻa oxidation maikaʻi a me ke kūpaʻa ʻano maikaʻi loa. He ductility maikaʻi ma hope o ka hoʻohana ʻana a me ka weldability maikaʻi loa.
Hoʻohana ʻia ʻo Ni90Cr10 no nā mea hoʻomehana uila i nā mea hana hale a me nā umu ahi. ʻO nā noi maʻamau he hao palahalaha, nā mīkini hao, nā mea hoʻomehana wai, nā mea hoʻoheheʻe plastik, nā hao hao, nā mea tubular sheathed metala a me nā mea pahu pahu.
Ma muli o nā waiwai adhesion maikaʻi loa o ka oxide o ka ʻili, hāʻawi ʻo Ni90C10 i ke ola lawelawe ʻoi aku ka maikaʻi ma mua o ka hoʻokūkū nickel-chromium alloys.

Hoʻohana ʻia ʻo CHROMEL vs ALUMEL i ka ea hoʻoemi ʻana, inert a maloʻo paha. Ua kaupalena ʻia ka ʻike ʻana i ka vacuum i nā manawa pōkole. Pono e pale ʻia mai ka sulfurous a me ka marginally oxidizing atmospheres. Hiki ke hilinaʻi a pololei i nā mahana kiʻekiʻe.Chromel: ʻO Chromel kahi huila o ka 90% nickel a me 10% chromium. Hoʻohana ʻia ia ma ka hana ʻana i nā mea hoʻokele maikaʻi o ANSI Type E a me Type K thermocouples, nā mea hana no ke ana ʻana i ka mahana i loaʻa i ʻelua conductors like ʻole.
