White fused alumina(WA) grit and powder
It is also named white corundum, white aluminium oxide .
Top quality, first grade, FEPA standard, JIS standard, China GB standard.
It has high purity of AL2O3 99%-99.9%.
It’s white color and has little higher hardness and toughness.
The abrasive tools made of it are suitable for fine grinding of high carbon steel, high-speed steel and stainless steel.
Abrasive powder of finer grit size, can also be used for precision casting and high-grade refractory, for sandblasting, and abrasive etc.
