Pink Fused Alumina F Grade's hardness is close to, but toughness higher than that of white aluminum oxide. The abrasive tools made of it feature excellent durability and high processing clean. Pink aluminium oxide (PA) is produced by bayer alumina and right quantity oxidized chromium in an electric arc furnace at high temperatures. The abrasive tools which made of PA have excellent durability and high processing cleanness. Our Pink Fused Alumina F Grade is manufactured from calcined alumina with a small addition of chrome. One of the toughest fused aluminas available, the addition of typically 0.2% chrome within the melt of the fusion process renders a tougher grain than that of white fused alumina. Made in a similar fashion using calcined alumina as white fused but the inclusion of chrome in the fusion process toughens the product and causes a colouring of the material.
