Black aluminum oxide F12#-F220# for cutting disc mixing with BFA
Black Fused Alumina, also called Black aluminum oxide, black
corundum emery powder, BA, ect., is smelt in tilting arc furnace
with bauxite, iron oxide as raw materials and added other
microelements. The strict melting process ensures the black
corundum high quality: few impurity, high grade and stable quality,
The grit, section sand and microgrits are with moderate hardness,
good toughness and excellent service performance.
