Isicelo:
I-Praseodymium Metal, isetyenziswa njenge-agent ye-alloying yamandla aphezulu kwi-Magnesium esetyenziswa kwiindawo zeenjini zenqwelomoya.Yi-agent ye-alloying ebalulekileyo kwimagnethi ye-Neodymium-Iron-Boron.I-Praseodymium isetyenziselwa ukwenza iimagnethi zamandla aphezulu eziphawuleka ngamandla kunye nokuqina kwazo.Ikwasetyenziswa kwizilayishi, iziqhushumbisi zetotshi, iziqalisi zomlilo 'zeflint kunye nentsimbi', njl. njl. I-Praseodymium Metal inokuqhubekekiswa ngakumbi kwiimilo ezahlukeneyo ze-ingots, amaqhekeza, iingcingo, iifoyile, amacwecwe, iintonga, iidiski kunye nomgubo. izongezo eziphathekayo, kunye nezongezo ze-alloys ezikumgangatho ophezulu, iimveliso zombane njalo njalo.
