Izixhobo zemagnethi ezisisigxina ze-Alnico azinakuyilwa njengenxalenye yolwakhiwo ngenxa yeempawu zamandla aphantsi oomatshini, ukuqina okuphezulu, ukuqaqanjelwa, kunye nokungafezeki kakuhle.Ukugaya okuncinci kuphela okanye i-EDM ingasetyenziselwa ngexesha lokucutshungulwa, ezinye iindlela ezifana nokukhwabanisa kunye nezinye izixhobo azikwazi ukusetyenziswa.
I-AlNiCo iveliswa ikakhulu ngendlela yokuphosa.Ukongeza, i-metallurgy engumgubo inokusetyenziselwa ukwenza imagnethi edibeneyo, enomsebenzi ophantsi kancinci.I-Cast AlNiCo inokucutshungulwa ngokweesayizi ezahlukeneyo kunye nokumila ngelixa iimveliso ze-AlNiCo ezifakiweyo zincinci.Kwaye izixhobo zokusebenza ze-sintered AlNiCo zinokunyamezela okubhetele komgangatho, iipropathi zemagneti zingaphantsi kancinane kodwa ubugcisa bungcono.
I-advanteji yemagnethi ye-AlNiCo i-remanence ephezulu (ukuya kwi-1.35T), kodwa ukunqongophala kukuba amandla okunyanzelisa aphantsi kakhulu (ngokuqhelekileyo angaphantsi kwe-160kA / m), kwaye ijika le-demagnetization alikho kumgca, ngoko ke i-AlNiCo yimagnethi elula ibe yimagnethi kwaye kulula ukuba yenziwe demagnetized.Xa uyilo lwesekethe yemagnethi kunye nokuveliswa kwesixhobo, ingqalelo ekhethekileyo kufuneka ihlawulwe kwaye umazibuthe kufuneka uzinziswe kwangaphambili.Ukuze uthintele i-demagnetization engagqibelelanga engajikiyo okanye ukugqwethwa kosasazo lwe-magnetic flux density, akuvumelekanga ngokungqongqo ukunxibelelana nazo naziphi na izinto ze-ferromagnetic ngexesha lokusetyenziswa.
Imagnethi esisigxina yeCast AlNiCo inowona mlinganiso wobushushu usezantsi ubuyiselwa umva phakathi kwezixhobo zemagnethi ezisisigxina, iqondo lobushushu elisebenzayo linokufikelela kuma-525°C, kunye nobushushu beCurie ukuya kuma-860°C, eyona nto isisigxina umazibuthe eneyona ndawo iphezulu yeCurie.Ngenxa yozinzo olulungileyo lobushushu kunye nokuzinza kokwaluphala, iimagnethi zeAlNiCo zisetyenziswa kakuhle kwiimotor, izixhobo, izixhobo zombane, kunye noomatshini bemagnethi, njl.
