Brown oksid aliminyòm
Korundum mawon se yon kalite materyèl ki pa metalik ki fèt ak materyèl boksit ki fonn pa gwo tanperati elektrik gwo founo dife, ki se Lè sa a, kraze ak chwazi nan espesifikasyon divès gwosè patikil. Karakteristik korundum mawon: kontni aliminyòm pi gran pase 95%, rezistans mete, presyon ...
Korundum mawon se yon kalite materyèl ki pa metalik ki fèt ak materyèl boksit ki fonn pa gwo tanperati elektrik gwo founo dife, ki se Lè sa a, kraze ak chwazi nan espesifikasyon divès gwosè patikil.
Karakteristik mawon korundum: kontni aliminyòm pi gran pase 95%, rezistans mete, rezistans presyon, bon fòs, sablaj se pa fasil kraze, kidonk li ka jeneralman itilize repete.
