BROWN FUSED ALUMINUM OXIDE POWDER
Brown Fused Aluminum Oxide Powders are the perfect material specifically manufactured to be used for general abrasive applications in bonded abrasive tools and lapping and polishing processes. While aluminum oxide has lower hardness and abrasive capacity than diamond, boron carbide, and silicon carbide, it is widely used for grinding ferrous materials, finishing tough and hard materials, filling up ceramic parts when the processing cost is important.
