Alnico magnet material is made by alloying aluminum, nickel and cobalt with ron. Ba'zi navlarda mis va/yoki titan ham mavjud. Qotishma jarayoni quyma yoki sinterlashdir, manetik xususiyatlarni optimallashtirish uchun zarur bo'lgan jarayon va ishlov berish abraziv silliqlash orqali eng yaxshi shaklga ega bo'lgan yoki tugatilgan qattiq (RC45) va mo'rt qismlarni ishlab chiqaradi, quyma qismlar odatda 70 funtdan past bo'ladi va ular sifatida ishlatilishi mumkin, but polar surfaces are usualy ground flat and paralel. Sintering is confined to hievolume parts in sizes under one cubic inch and an effective press length to diameter ratio under four
