1.  White fused alumina oxide Description

White fused aluninium abrasives is electrically fused in the fuenace with high-grade alumina powder as raw materials.It has higher hardness and slightly lower toughness than brown fused aluminium oxide,characte-rized by its high purity,strong grinding ability,Abrasive tools made of it are suitable for grinding highspeed steel,high carton steel,etc.It also can used as materials for grinding and polishing precision-casting,spraying and coating,medium body for chemical industry,special ceramics and high-grade refractory materials,etc.
