Nichrome, makwaara dị ka Nickel Chrome, bụ alloy na-emepụta site na ịgwakọta nickel, Chromium na, mgbe ụfọdụ, ígwè. Kacha amara mara maka nguzogide okpomoku ya, yana iguzogide ha na corrosion na oxidation, alloy a bara uru maka otutu ngwa. Site na imepụta ihe omume ntụrụndụ, nichrome n'ụdị waya dị na ngwaahịa ngwaahịa, ọrụ na ngwaọrụ. Ọ chọkwara ngwa na ntọala pụrụ iche.

Nchrome waya bụ alloy mere site na Nickel na Chromium. Ọ na-eme ka ọkụ na ọpụpụ ma na-eje ozi dị ka ihe na-ekpo ọkụ na ngwaahịa dị ka ndị na-ata ahịhịa na ndị na-ehicha ntutu. Ndị na-ahụ maka ndị na-ahụ maka Nichrome waya na saramiiki ọkpụkpọ na iko. Enwere ike ịchọta waya ahụ na ụlọ nyocha, iwu na elektrọnik.

N'ihi na waya waya na-eguzogide ọkụ eletrik, ọ bara uru dị ka ihe na-ekpo ọkụ na ngwaahịa na ngwaọrụ ụlọ. Inye aka na ndị na-ehicha ntutu na-eji cils nke waya waya iji mepụta nnukwu okpomọkụ, dị ka overs toaster na ndị na-ere ọkụ. Ikike mmepụta ọrụ na-ejikwa waya waya arụ ọrụ. Enwere ike iji ogologo nke nichrome mepụta waya cutter, nke enwere ike iji ya ma ọ bụ na ọnọdụ ime ụlọ mmepụta ihe iji belata ma kpụọ ụfụfụ ụfọdụ na plastik.

A na-eji eriri elom na-abụghị nke magnetic nke sitere na nickel, chromium na iron. A na-eji ihe ngosi na-egosipụta na ya na-eguzogide na nguzogide oxidation. Nchrome waya nwekwara ezigbo ntukwasi obi mgbe o jiri ma na-agbagha.

Nọmba ahụ na-abịa mgbe ụdị waya waya na-egosi pasent nke Nickel na alloy. Dịka ọmụmaatụ, "Nichrome 60" nwere ihe dị ka 60% nickel na ihe mejupụtara ya.

Ngwa maka waya waya gụnyere ihe kpo oku nke nkụ na-ehicha ntutu, ndị na-eme ka ọkụ, na nkwado seramiiki na kilomita.
