The type of white fused alumina suitable as a sandblasting abrasive is mainly determined by the purity grade and particle size specification of the product, which can be selected according to different sandblasting requirements such as processing precision, workpiece material and cost budget. The specific suitable types and their application scenarios are as follows: By purity grade High-purity white

The ball milling toughness and fracture resistance of white fused alumina (WFA) are directly positively correlated, inherently homologous, but distinct in evaluation dimensions—ball milling toughness serves as a standardized quantitative indicator to measure fracture resistance, while fracture resistance is the core mechanical property reflected by ball milling toughness. Both originate from WFA’s intrinsic material characteristics, with
