Pembekal Cina Nichrome 90 NI90
NI90cr10 mangrupikeun anénal-noyel-kracoy alloy (Nicr Alooy) pikeun dianggo dina suhu nepi ka 1200 ° C (2190 ° F). Sakabeuk dicirikeun ku gangguanah Éta ngagaduhan dukuran anu saé saatos dianggo sareng weldability anu saé.
Ni90cr10 dianggo pikeun unsur pemanasan listrik di alat bumi sareng perhatosan industri. Opstik umum nyaéta iron daton, mesin beusi, paman pemanis, kardis plass, iron daya tarik sareng unsur kartrid.
Kusabab pisan sipat adupsion anu saé permukaan Ocdere, NI90C10 nawiskeun kahirupan Ladénimasi anu unggul dibandingkeun sareng nikel sareng kromium kroko.

Chromel vs alumel dianggo dina dioksidasi, inert atanapi garing ngirangan atmosfle. Paparan kana vakum terbatas kana waktos anu lami. Kedah dilindungi tina sulfurous sareng atgosfher Kaluaran sareng akurat dina suhu anu luhur.Chromel: kromel mangrupikeun aloi anu diperkirakeun 90% nikel sareng 10% kromium. Éta dianggo dina kamragungan pelaku positip ASI ngandung é sareng jinis k thhomocou, alat pikeun ngukur suhu anu diwangun ku dua kondisi anu béda.
