brown fused alumina in abrasives grit corundum
This abrasive is produced from artificial corundum through fusion processes. Aluminum Oxide Abrasive distributed is an extremely tough material, registering a value of 9.0 on the Mohs scale.
Aluminum oxide particles are extremely tough and sharp, with high cutting and cleaning speeds, being effective for fast and aggressive sandblasting. Fine abrasive particles produce a very smooth finish to sandblasted surfaces, and grungy particles cut in depth, removing all deposits on the surfaces.
Due to the high hardness, this material is used successfully for blasting processes that require great force and speed.This material is of high purity and is ideal for sanding surfaces that are not allowed to impregnate with other substances during the blasting process: INOX, Aluminum, Copper.Aluminum oxide is used successfully for cleaning, deburring, surface finishing, rust removal and old paint coatings, preparing surfaces for subsequent anti-corrosion treatments with paint and primer at the highest quality standards.
