#30 Grit White Fused Alumina With Good Toughness And High Refractory Temperature For Abrasive Tools

#30 Grit White Fused Alumina With Good Toughness And High Refractory Temperature For Abrasive Tools
 

White Fused Alumina is a synthetic Fused Alumina made of reduced fusion of high purity aluminum Oxider powder and other fillings in electric arc furnace under 2000 degrees above. Its main chemical content is Al₂O₃(99% min), little Na₂O, Fe₂O₃ and SiO₂.

#30 White Fused Alumina is a medium-coarse abrasive with high hardness, high purity and low iron content. It features strong cutting force, good toughness and stable performance, suitable for rough grinding, heavy deburring and efficient surface treatment. It does not contaminate workpieces and is widely used in grinding wheels, sandblasting and metal surface processing.
