What are the different types of sandpaper and what are they used for?
Aluminum Oxide – A synthetic brown-colored mineral that is tough and durable and is the most widely used abrasive grain. It is ideal for both woodworking and metalworking. (Non-Ferrous) Silicon Carbide – A very hard and shiny black-colored mineral. This product has a brittle quality that allows it to fracture into sharp sliver-like wedges as it works. Can be used for everything from sanding non-ferrous and ferrous metals, plastics, composites, and wood products. Garnet – A reddish brown mineral. It is of medium hardness with good cutting edges and has the tendency to break or fracture when used, thus creating new cutting edges. Used primarily for fine finishing of wood.
