Co50V2 Ígwè Cobaltbụ ike ndọta saturation nke ígwè, cobalt, na vanadium dị nro magnetik alloy. N'ime alloys magnetik dị nro dị ugbu a, calcium alloy nwere ike ndọta saturation kachasị elu (2.4 T), yana oke okpomọkụ Curie (980 ºC), oke magnetostriction saturation nke kachasị (60 ~ 100 * 10 6).

N'ihi oke ike ndọta nke na-eme ka ihe dị n'ime ya dị elu, mgbe ọ na-eme moto ike nhata, ọ nwere ike ibelata olu ya nke ukwuu, mgbe ọ na-eme electromagnet, n'okpuru otu mpaghara obe ahụ, ọ nwere ike imepụta ike ịmịnye ya nke ukwuu.

N'ihi oke Curie ha, enwere ike iji alloy ahụ mee ihe na ihe ndị ọzọ dị nro nke magnetik alloy nke emebiela kpamkpam n'okpuru oke okpomọkụ, ma nọgide na-enwe ezigbo nkwụsi ike magnetik.

N'ihi nnukwu ọnụọgụgụ magnetostrictive, ma dịkwa mma maka iji ya dị ka ihe na-agbanwe magnetostrictive, ike mmepụta dị elu, arụmọrụ ya dị elu. Nguzogide nke obere alloy (0.27 μΩ m.), adabaghị maka ojiji n'okpuru ugboro ugboro dị elu. Ọnụahịa ya dị elu, ọ dị mfe iwepụ ya ngwa ngwa, arụmọrụ nhazi ahụ adịghịkwa mma; itinye nickel ma ọ bụ ihe ndị ọzọ kwesịrị ekwesị nwere ike ime ka arụmọrụ nhazi ahụ ka mma.

Ngwa: dabara adaba maka ime ka mma dị mfe, obere olu nke ụgbọelu na ụgbọ elu mbara igwe nwere ihe eletriki, dịka, isi pole magnet micro-moto rotor, relays, transducers, wdg.
