Ni90Cr10 minangka nikel krmium Austenit (Nicr Alloy) kanggo digunakake ing suhu nganti 1200 ° C (2190 ° F). Aloi ditondoi kanthi resektivitas sing dhuwur, resistensi oksidasi sing apik lan stabilitas sing apik banget. Nduwe duktabilitas sing apik sawise nggunakake lan welasan sing apik.
Ni90CR10 digunakake kanggo unsur pemanasan listrik ing peralatan omah lan tungku industri. Aplikasi khas yaiku mesin iring, pemanasan banyu, ngecor plastik mati, soldering iron, unsur tubular logam lan unsur kartun.
Amarga sipat adhesion sing apik banget ing permukaan oksida, ni90c10 nawakake urip layanan sing luwih unggul dibandhingake karo wesi-wesi kromium sing kompetitif.

Chromel vs Alumel digunakake ing ngoksidasi, inert utawa garing atmosfer. Cahya kanggo vakum diwatesi wektu sing cendhak. Kudu dilindhungi saka sulfurous lan atmosferes ngoksidasi. Dipercaya lan akurat ing suhu dhuwur.chromel: Chromel minangka wesi nikel 90% lan kromium 10%. Iki digunakake kanggo pabrik saka konduktor positif saka jinis E lan jinis termocouples, piranti kanggo suhu sing ngukur dumadi saka rong konduktor sing beda.
