Choosing between white fused alumina and tabular alumina for ultra-high-temperature refractories is a structural decision, not just a cost comparison. This article examines the microstructural, thermal, and chemical properties that determine which material survives sustained service above 1600 °C — and where each grade delivers the better return on refractory investment.
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.
Choosing between white and brown fused alumina for blasting comes down to four variables: substrate chemistry, anchor profile target, recycling economics, and downstream process sensitivity. This guide compares hardness, friability, iron content, and cost-per-cycle, with a decision matrix and PO checklist to specify the right grade with confidence.
