Product Description
Black fused alumina is a kind of artificial abrasives which has proper hardness, high toughness, good self-sharpening, high hydrophilicity, high heat conductivity and bonding ability.
It can achieve better effects when combined with brown fused alumina (BFA) to produce grinding wheels and cut-offs than BFA, and the addition of BA can be 15% to 45%. More importantly, the use of BA can cut down the cost of your products.
