Samarium Cobalt magnet
Samarium cobalt magnetik, ihe ndị bụ isi bụ samarium na cobalt.N'ihi na ọnụ ahịa ihe dị oke ọnụ, samarium cobalt magnet bụ otu n'ime ụdị dị oke ọnụ.
Ngwaahịa ike magnetik nke samarium cobalt magnet nwere ike iru 30MGOe ugbu a ma ọ bụ karịa.Tụkwasị na nke ahụ, ihe ndọta samarium cobalt bụ nke na-amanye na oke okpomọkụ na-eguzogide ya, a pụkwara itinye ya na okpomọkụ ruo 350 degrees Celsius.Ya mere na ọ bụ irreplaceable na ọtụtụ ngwa
Samarium cobalt magnet bụ nke ngwaahịa metallurgy ntụ ntụ.Ndị na-emepụta ihe n'ozuzu dịka nha na ọdịdị nke mkpa ngwaahịa emechara, na-ere ọkụ n'ime oghere square, wee jiri eriri diamond bee n'ime nha nke ngwaahịa emechara.N'ihi na samarium cobalt na-eduzi ọkụ eletrik, enwere ike ịkpụ ya n'ahịrị.N'ụzọ doro anya, samarium cobalt nwere ike ịkpụ n'ime ọdịdị nke nwere ike ịkpụ n'ahịrị, ma ọ bụrụ na a naghị atụle magnetization na nnukwu nha.
Samarium cobalt magnetik nwere ezigbo nguzogide corrosion na n'ozuzu anaghị achọ mgbochi corrosion plating ma ọ bụ mkpuchi.Na mgbakwunye, samarium cobalt magnets na-agbaji, ọ na-esiri ike ịmepụta ngwaahịa na obere nha ma ọ bụ mgbidi dị mkpa.
Alnico magnetik
Alnico magnet nwere nkedo na sintering abụọ dị iche iche usoro ụzọ.Ime na-emepụta ihe nkedo karịa Alnico.Ngwaahịa ike magnetik nke Alnico magnet nwere ike ruo 9MGOe, ma nwee nnukwu njirimara bụ nke na-eguzogide okpomọkụ dị elu, okpomọkụ na-arụ ọrụ nwere ike iru 550 degrees Celsius.Otú ọ dị, Alnico magnetik dị nnọọ mfe demagnetize na ihe ndọta ntụgharị uche.Ọ bụrụ na ị na-agbanye ogwe ndọta Alnico abụọ n'otu ụzọ (abụọ N's ma ọ bụ abụọ S) ọnụ, a ga-eweghachi ma ọ bụ tụgharịa mpaghara nke otu n'ime magnetik.Ya mere, ọ dịghị mma maka ịrụ ọrụ na oghere magnetik (dị ka moto).

Ferrite magnet / seramiiki magnetik
Ferrite bụ ụdị ihe ndọta na-abụghị metallic, nke a makwaara dị ka seramiki magnetik.Anyị na-ewepụ redio a na-ahụkarị, ma ndọta mpi dị na ya bụ ferrite.
