The main component of white fused alumina is α-Al₂O₃, with a purity generally above 99%. Its crystal form and thermal expansion coefficient are highly consistent with those of alumina ceramic matrices. Featuring low impurity content, high hardness and excellent chemical stability, it serves as a core raw material and supporting consumable for alumina ceramic manufacturing.

White Fused Alumina Micropowder for Coatings White fused alumina micropowder features excellent wear resistance, scratch resistance, acid and alkali resistance, high whiteness, UV resistance and other properties. Therefore, it is the most commonly used hard filler for industrial coatings, including epoxy flooring coatings, anti-corrosion paints, polyurethane coatings, powder coatings, wear-resistant topcoats and industrial anti-slip coatings.

1. Product Advantages Aerospace parts are made of titanium alloy, nickel-based superalloy, aviation aluminum and stainless steel. Even tiny iron impurities will cause corrosion, coating peeling and anodizing failure. Therefore, high-purity white fused alumina is the only qualified blasting abrasive for aerospace applications. Ultra-high purity & zero iron pollution: Al₂O₃ ≥99.5%, Fe₂O₃ ≤0.05%, TiO₂ ≤0.1%.

White Fused Alumina 150# for Aluminum Tube Sandblasting 1. Application Suitability Aluminum is soft in texture, prone to denting, sand embedding and oxidation discoloration. White fused alumina 150# (F150) is a widely used grade for aluminum tube sandblasting. Made of high-purity alumina with no iron impurities; no rust spots or contamination will form on aluminum

White Fused Alumina Micropowder for Thermal Insulation Coatings Chemical Composition of White Fused Alumina Micropowder Affecting the Performance of Thermal Insulation Coatings Al₂O₃: ≥ 99.2–99.7% Na₂O: ≤ 0.25% Physical & Chemical Indicators of White Fused Alumina Micropowder for Thermal Insulation Coatings Color: Pure white; whiteness ≥ 88, will not cause discoloration for light-colored / white

I. Basis for selecting alumina / white fused alumina grades Grade selection depends on the target abrasion resistance of the finished wear-resistant melamine paper. Abrasion performance is directly related to particle size: Coarser particles deliver better abrasion resistance but reduce the transparency of melamine paper. Finer particles offer relatively lower abrasion resistance while significantly improving
