Product Details

NO.6 Coated White Fused Alumina

Flagship coated abrasive for premium abrasive disc manufacturing

As top-grade coated abrasive material, NO.6 owns stable chemical composition and excellent mechanical performance. Supported by high grain toughness, it effectively withstands impact and wear, lowering particle breakage during use.

Dense grain structure and reasonable particle gradation ensure steady cutting and grinding effect. Optimized coating property enables firm combination with resin binder, minimizing grain shedding. Finished abrasive discs maintain stable quality, long service life and consistent working performance.
