Ko te Ni90Cr10 he koranu nickel-chromium austenitic (NiCr alloy) hei whakamahi i te mahana ki te 1200°C (2190°F). Ko te koranu e tohuhia ana e te resistivity teitei, te pai o te waikura me te tino pai o te ahua. He ductility pai i muri i te whakamahi me te pai weldability.
Kei te whakamahia a Ni90Cr10 mo nga waahanga whakawera hiko i roto i nga taputapu whare me nga oumu ahumahi. Ko nga tono angamaheni he rino papatahi, mihini rino, whakamahana wai, mate hangai kirihou, rino whakapiri, huānga ngongo pukoro whakarewa me nga huānga kariri.
Na te tino pai o te whakaurunga o te waikura o te mata, ka tukuna e Ni90C10 te oranga ratonga pai ake ki te whakataetae nickel-chromium alloys.

Kei te whakamahia a CHROMEL me te ALUMEL ki te whakapouri, ki te koretake, ki te whakamaroke ranei i nga hau whakaheke. He wa poto noa te whakakitenga ki te korehau. Me whakamarumaru mai i nga hau whanariki me te waikura iti. He pono, he tika hoki i nga wera teitei.Chromel: Ko te Chromel he koranu o te 90% nickel me te 10% chromium. Ka whakamahia i runga i te hanga o nga kaikawe pai o ANSI Momo E me Momo K thermocouples, nga taputapu mo te ine i te pāmahana e rua nga kaikawe rereke.
