Aluminum Oxide vs Silicon Carbide Sandpaper | Uneeda

May 01, 2018· Silicon carbide is a sharper and harder grain compared to aluminum oxide, but silicon carbide is less durable because it is brittle and has a more narrow shape that wears down at an increased rate. Due to its razor-sharp grains, silicon carbide will have no problem easily cutting glass, plastic, and metal under light pressure.
