Pink Aluminium Oxide abrasive is electrically fused from alumina and other materials. The pink colored abrasives has hardness similar and toughness greater than white aluminum oxide. Grinding wheels made of pink aluminum oxide have the features of outstanding durability and producing fine surface finish. Suitable for precision grinding applications with metrology instruments, engine crankshafts, instrument parts, threads and samplers.

I am very satisfied with its performance and quality. It is a durable and efficient abrasive that can grind and polish various materials.
I have no experience with brown fused alumina. However, based on the web search results, I can say that brown fused alumina is a high-performance abrasive and refractory material.
