Ni80Cr20he koranu nickel-chromium (NiCr alloy) e tohuhia ana e te parenga teitei, te pai o te waiora me te tino pai o te ahua. He pai mo te whakamahi i te pāmahana tae atu ki te 1200°C, me te pupuri i te oranga o te ratonga pai ake i whakaritea ki te rino chromium alumium alloys.
Ko nga tono angamaheni mo Ni80Cr20 he huānga whakawera hiko i roto i nga taputapu kaainga, oumu ahumahi me nga parenga (nga parenga waea, nga parenga kiriata whakarewa), rino papatahi, mihini rino, whakamahana wai, mate hangai kirihou, rino whakapiri, huānga ngongo me nga huānga kariri.
