Spherical Alumina Pa'u mo Mea Fa'afeso'ota'i vevela
Fa'amatalaga o oloa
HRK fa'asologa spherical alumina e gaosia e ala i le maualuga o le vevela o le fa'afefeteina o le fa'atupuina o foliga masani Al2O3, ona faia lea o su'esu'ega, fa'amamāina ma isi faiga e maua ai le oloa mulimuli.O le alumina maua e maualuga le maualuga o le spheroidization, fa'atonuina le tufatufaina o le tele o vaega ma maualuga le mama.Ona o ona uiga faʻapitoa e pei o le maualuga o le faʻauluina o le vevela ma le feʻaveaʻi lelei, O le oloa na faʻaaogaina lautele e pei o le faʻatumuina o mea faʻaoga faʻafefe, palasitika faʻainisinia vevela ma alumini-faʻavae Copper-Clad Laminates ma isi.
