Aluminum Oxide vs Silicon Carbide Sandpaper | Uneeda

2019-4-21 · 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.

In addition, it is characterized by the fact that SiC can resist

Why is aluminum oxide used more frequently than …

2007-8-2 · Best Answer: Aluminum oxide is tougher and therefore better suited to grinding steel, and a lot of grinding is done on steel. Silicon carbide is harder, but quite brittle, it tends to break into sharp shapes which is an advantage for nonferrous and nonmetallic workpieces, but the lack of toughness makes it specialized abrasive and therefore it is used less than aluminum oxide.
