Brown Fused Alumina is a tough, sharp abrasives which is highly suitable for grinding metals of high tensile strength. Its thermal properties make it an excellent material for use in the manufacture of refractory products. This material is also used in other applications like blasting and surface hardening.

Application:
- production of a broad range of abrasive tools, e.g. grinding wheels, abrasive segments, etc. that are designed for processing durable articles, above all for steel processing,
- production of abrasive papers and clothes,
- in fireproof and ceramic industry,
- in sand-blast processing.
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.
PROPERTIES
- Offered in macro and micro powder form in both P and FEPA grades
APPLICATIONS
- Grinding ferrous materials
- Finishing tough and hard materials
- Filling up ceramic parts when the processing cost is important
