People frequently start by rough sanding raw woods or metal with aluminum oxide abrasives before moving on to silicon carbide for light pressure sanding between coats. Nonwoven abrasives like belts, discs, and wheels often contain both materials. Zirconia lasts longer and is more friable than aluminum oxide, yet comes at a premium cost. It works great on metals and rough surfaces such as polishing automotive parts, removing rust from wood floors, deburring metal parts, or smoothing glass edges – providing lasting solutions at competitive prices. Hardness Silicon carbide is a much harder and more durable abrasive grain than aluminum oxide, making it perfect for rough sanding materials such as paint, …
