Ni80Cr20 o se nickel-chromium alloy (NiCr alloy) o loʻo faʻaalia i le maualuga o le teteʻe, lelei le faʻamaʻiina o le faʻamaʻiina ma le faʻamautuina lelei o foliga. E fetaui lelei mo le faʻaaogaina i le vevela e oʻo atu i le 1200 ° C, ma umia se olaga sili atu le tautua pe a faʻatusatusa i le uʻamea chromium alumium.
O faʻaoga masani mo Ni80Cr20 o elemene faʻavevela eletise i meafale, ogaumu fale gaosimea ma faʻalavelave (faʻalavelave uaea, faʻamaʻi ata tifaga), uʻamea mafolafola, masini uʻamea, faʻavevela vai, paʻu palasitika paʻu, uʻamea faʻapipiʻi, elemene tubular faʻapipiʻi uʻamea ma elemene kalama.
