Ni80cr20 ko te nickel-chromium ally (nicr alloy) e whakaatuhia ana e te patoitanga nui, te pai o te ātete o te hāora, me te tino pai. He mea tika mo te whakamahi i te pāmahana ki te 1200 ° C, me te pupuri i tetahi mahi ratonga pai ki te whakakapi i te rino konumoana rino.
Ko nga tono angamaheni mo te ni80cr20 he huanga whakawera hiko i roto i nga taputapu taputapu kaainga, nga oko o te whare, nga miihini miihini, nga kowhatu kirihou.
