White fused alumina with ≥99.5% Al₂O₃ purity and controlled grain morphology is the reference abrasive for plateau honing hydraulic cylinder bores to Ra 0.2–0.8 µm tolerances required by high-pressure seal systems. This guide covers grit selection by honing stage, critical material specifications, and pressure-class-specific finish targets to help engineers and procurement teams specify correctly.
