Product Details

Low Na2O less than 0.2% white fused alumina

Low sodium white fused alumina means white corundum with Na2O＜0.2%. The Na2O content will affect the hardness, temperature compressive strength and bending resistance strength, etc. With a special smelting process, HAIXU Abrasive presents Na2O within 0.2% and Na2O within 0.1% WFA grain and powder which are sutiable for high-level refractory and abrasive tools.
