mawon oksid aliminyòm

Korundon mawonse 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, rezistans presyon, bon fòs, sablaj se pa fasil kraze, kidonk li ka jeneralman itilize repete.
