Alnico Magnet is de legere magneet fan aluminium, nikkel, kobalt, izer en oare spoarmetalen eleminten, dat is de earste generaasje fan permaninte magneet materialen dy't op it betiidst ûntwikkele.
Alnico Permanent Magnet materialen hawwe it foardiel fan hege Br (oant 1.5T) en lege temperatuer koëffisjint, stabile magnetyske, hege temperatuer ferset, focht ferset en oksidaasje ferset.As de temperatuerkoëffisjint -0.02% / ℃ is, kin de maksimale wurktemperatuer 550 ℃ berikke.It neidiel is dat de koerciviteit tige leech is en de demagnetisaasjekromme net-lineêr is.Dêrom, hoewol Alnico-magneten maklik magnetisearre wurde, binne se ek maklik om te demagnetisearjen.
Neffens it produksjeproses kin it wurde ferdield yn Sintered Alnico en Cast Alnico.De foarm fan it produkt is meast rûn en fjouwerkant.Casting proses kin wurde ferwurke yn ferskillende maten en foarmen;
Yn ferliking mei it casting proses is de sintered produkt beheind ta lytse grutte produkten.De dimensionale tolerânsje fan sintere blanks is better dan dy fan it getten produkt, wylst de magnetyske eigenskippen wat leger binne as dy fan it getten produkt
Alnico wurdt no in soad brûkt yn magneto-elektryske ynstruminten, elektromagnetyske flowmeters, relais, learynstruminten, elektryske gitaar pickups, mikrofoans, sensoren, reizgjende golfbuizen, komagneten en oare fjilden.
