Nichrome, nke a makwaara dị ka nickel chrome, bụ ihe alloy na-emepụta site na ịgwakọta nickel, chromium na, mgbe ụfọdụ, ígwè. Nke kacha mara amara maka nguzogide okpomọkụ ya, yana nguzogide ya na corrosion na oxidation, alloy na-aba uru nke ukwuu maka ọtụtụ ngwa. Site na nrụpụta ụlọ ọrụ na-arụ ọrụ ntụrụndụ, nichrome n'ụdị waya dị n'ụdị ngwaahịa azụmaahịa, nka na ngwaọrụ. Ọ na-ahụkwa ngwa na ntọala pụrụ iche.
Nichrome waya bụ ihe alloy mere site na nickel na chromium. Ọ na-eguzogide okpomọkụ na oxidation ma na-eje ozi dị ka ihe na-ekpo ọkụ na ngwaahịa ndị dị ka toasters na igwe nkụ.

N'ihi na waya nichrome na-eguzogide ọkụ eletrik, ọ bara uru nke ukwuu dị ka ihe na-ekpo ọkụ na ngwaahịa azụmahịa na ngwá ọrụ ụlọ. Ndị na-ekpo ọkụ na ndị na-ehicha ntutu na-eji eriri nichrome waya na-emepụta oke ọkụ, dị ka oven na ọkụ ọkụ na-eme. Igwe ọkụ ụlọ ọrụ na-ejikwa waya nichrome arụ ọrụ. A pụkwara iji ogologo waya nichrome mee ka onye na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ, nke a pụrụ iji mee ihe ma n'ụlọ ma ọ bụ na ụlọ ọrụ mmepụta ihe iji gbutu na ịkpụzi ụfọdụ ụfụfụ na plastik.
A na-eme waya nichrome nke na-abụghị ihe ndọta nke sitere na nickel, chromium, na ígwè mejupụtara. Nichrome bụ ihe e ji mara ya dị elu resistivity na ezigbo oxidation resistance. Nichrome waya nwekwara ezigbo ductility mgbe ejiri ya na ọmarịcha weldability.
Ọnụọgụ na-abịa mgbe ụdị waya Nichrome na-egosi pasentị nke nickel na alloy. Dịka ọmụmaatụ, "Nichrome 60" nwere ihe dịka 60% Nickel na nhazi ya.
Ngwa maka waya Nichrome gụnyere ihe ndị na-ekpo ọkụ nke ndị na-ehicha ntutu, ihe mkpuchi ọkụ, na nkwado seramiiki na kilns.
