Does aluminum oxide remove rust?

Aluminum oxide, also known as alumina, is a hard, chemically stable inorganic compound with high melting point and excellent wear resistance, and it is widely used as an abrasive material, ceramic raw material, and catalyst carrier. It cannot directly dissolve or convert rust chemically, but its hard particles can physically remove rust by grinding and polishing metal surfaces, making it a common component in sandpaper, grinding wheels, and rust removal polishing pastes.
