Ni90Cr10 minangka paduan nikel-kromium austenitik (paduan NiCr) kanggo digunakake ing suhu nganti 1200°C (2190°F).Wesi kasebut ditondoi kanthi resistensi dhuwur, resistensi oksidasi sing apik lan stabilitas bentuk sing apik banget.Wis ductility apik sawise nggunakake lan weldability banget.
Ni90Cr10 digunakake kanggo unsur pemanas listrik ing peralatan omah lan tungku industri.Aplikasi khas yaiku wesi datar, mesin setrika, pemanas banyu, cetakan plastik, wesi solder, unsur tubular dilapisi logam lan unsur kartrid.
Amarga sifat adhesi sing apik banget saka permukaan oksida, Ni90C10 nawakake umur layanan sing unggul dibandhingake karo paduan nikel-kromium sing kompetitif.

CHROMEL vs ALUMEL digunakake ing oksidasi, inert utawa garing ngurangi atmosfer.Paparan vakum diwatesi kanggo wektu sing cendhak.Sampeyan kudu dilindhungi saka atmosfir sulfur lan oksidasi sing sithik.Bisa dipercaya lan akurat ing suhu dhuwur.Chromel: Chromel minangka paduan saka kira-kira 90% nikel lan 10% kromium.Iki digunakake kanggo nggawe konduktor positif ANSI Type E lan Type K thermocouple, piranti kanggo ngukur suhu sing dumadi saka rong konduktor sing beda.
