Nickel Chrome (NiCr) alloys bụ ihe nguzogide dị elu nke a na-ejikarị na ngwa nwere oke okpomọkụ na-arụ ọrụ ruo 1,250°C (2,280°F).

Amara Austenitic alloys ndị a maka ike ọrụ ha dị elu na okpomọkụ ma e jiri ya tụnyere FeCrAl alloys yana ike ha dị elu. Nickel Chrome alloys na-anọgide na-enwekwu ductile ma e jiri ya tụnyere FeCrAl alloys mgbe ogologo oge na okpomọkụ. A na-emepụta Chromium Oxide gbara ọchịchịrị (Cr2O3) n'ogo dị elu nke nwere ike ịpụpụ, ma ọ bụ na-agbagharị, na-ebute mmetọ nwere ike dabere na ngwa ahụ. Nke a oxide enweghị ihe mkpuchi ọkụ eletrik dị ka Aluminom Oxide (Al2O3) nke FeCrA alloys. Alloys Nickel Chrome na-egosipụta ezigbo nguzogide corrosion ewezuga na gburugburu ebe sọlfọ dị.
