Ni90Cr10 he Austenitic NICKEL-Chromium alloy (nicr alloy) hei whakamahi i te pāmahana ki te 1200 ° C (2190 ° F). Ko te arena e tohuhia ana e te taikaha nui, te pai o te whakaekenga o te waikawa me te tino pai. He pai te kohinga i muri i te whakamahi me te pai o te mahi.
Ka whakamahia te ni90Cr10 mo nga waahanga whakawera hiko i roto i nga taputapu taputapu kaainga me nga momo ahumahi. Ko nga tono angamaheni he paparanga angatahi, he miihini rino, nga wera o te wai, ka mate te kirihou, nga kaakahu i nga waahanga kapohia nga huanga o te kaata.
Na te mea he tino pai nga taonga o te kohinga mata, ni90c10 e tuku ana i te koiora ratonga pai ki te whakataetae Nickel-Chromium Apolium.
