How to identify the quality white fused alumina abrasive

Density is also an important indicator. The density of white fused alumina abrasives is divided into the packing density of white corundum and the true density of white fused alumina.

The packing density of white fused alumina abrasive is 1.53-1.99 g/cm3. The packing density of the abrasive depends on the grain size, grain size composition, type, grain shape, and other factors. In general, coarse-grained abrasives have higher packing density than fine-grained abrasives. The packing density of abrasive particles is greater than that of the individual particle size.

The actual density of white fused alumina abrasives: the density of white fused alumina abrasive particles is 3.95-4.0 g/cm3. The actual density of the abrasive refers to the mass of the abrasive contained in the unit volume (excluding the volume of the opening).

Specializes in the production of white fused alumina abrasives with high purity, good inherent sharpness, acid, and alkali corrosion resistance, high temperature resistance, and stable thermal performance. Hardness is slightly higher than brown fused alumina, toughness is slightly lower, purity is high, and self-sharpness is good. Strong grinding ability, low heat, high efficiency, acid, and alkali corrosion resistance, high temperature resistance, and good thermal stability.
