Ni90Cr10 mangrupakeun austenitic nikel-kromium alloy (NiCr alloy) pikeun pamakéan dina suhu nepi ka 1200 ° C (2190 ° F). alloy nu dicirikeun ku résistansi tinggi, résistansi oksidasi alus sarta stabilitas formulir pohara alus. Cai mibanda ductility alus sanggeus pamakéan sarta weldability alus teuing.
Ni90Cr10 dianggo pikeun elemen pemanasan listrik dina alat-alat bumi sareng tungku industri. Aplikasi ilaharna nyaéta irons datar, mesin ironing, pamanas cai, molding palastik paeh, soldering irons, logam sheathed tubular elemen sarta elemen cartridge.
Kusabab sipat adhesion anu saé pisan tina oksida permukaan, Ni90C10 nawiskeun umur jasa anu langkung saé dibandingkeun sareng alloy nikel-kromium kalapa.

CHROMEL vs ALUMEL dianggo dina atmosfir pangoksidasi, inert atanapi garing. Paparan vakum dugi ka période waktos pondok. Kedah ditangtayungan tina atmosfir sulfur sareng pangoksidasi marginal. Bisa dipercaya jeung akurat dina temperatures.Chromel luhur: Chromel mangrupa alloy tina hiji diperkirakeun 90% nikel jeung 10% kromium. Hal ieu dipaké dina fabrikasi tina konduktor positif ANSI Tipe E sarta Tipe K thermocouples, alat pikeun ngukur suhu diwangun ku dua konduktor béda.
