Pó de óxido de alumínio marrom

Brown Aluminum Oxide Powder is the perfect material manufactured explicitly for general abrasive applications in bonded abrasive tools and lapping and polishing processes. While aluminum oxide has a 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. Brown fused aluminum oxide is offered in macro and micro powder form, in JIS, GB, P, and FEPA grades.
