Aluminium Oxide is very slightly softer than silicon carbide but  it breaks down into smaller particles quicker than silicon carbide. It is a commonly used abrasive because it has a high metal removal rate but gives a smoother finish than silicon carbide.

Silicon Carbide is just below diamond for hardness and more aggressive than aluminum oxide . The particle shape is a bit sharper and the grains do not break up as easily. It removes metal quicker and leaves a “rougher” finish than aluminum oxide.
