Silicon carbide

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. However, hardwoods and metals will present more of a challenge. Regardless of sanding wood or metal, silicon carbide and aluminum oxide can be effectively paired together on the same sanding project, especially in woodworking applications.

vs

Aluminum Oxide

Regardless of if you are sanding wood or metal, aluminum oxide is the most frequently used grain in the industry because it does a pristine job on a number of materials including bare wood, painted surfaces, and metal. Additionally, aluminum oxide is exceedingly durable. The combination of very good shelf life and lower cost is what makes aluminum oxide stand out over other forms of sandpaper, including silicon carbide
When sanding harder metals such as titanium or stainless steel, aluminum oxide does not have as long of a life as Silicon carbide. Silicon carbide has better durability and runs cooler than aluminum oxide when applied to hard metal surfaces. 

For sanding is to start out using a lower-number, coarse grit before progressing to higher-numbered grits to add a finer touch.
