Four Basic Types of Abrasives
In the world of abrasives, there are basically four different types: Aluminum Oxide, Zirconium, Silicon Carbide, and Ceramic.
When choosing an abrasive, it is a mistake to let initial cost make your decision for you. Analysis of the application, cost per piece, lifetime of the material, and scrap should all be considerations when choosing the right abrasive for the job.
Aluminum oxide is an entry level abrasive. Of the four, it is the lowest cost and has the most general uses. Aluminum oxide abrasives can be used in belt sanding, power sanding or for hand sanding applications. These abrasives are available in a range of backing materials and closed coatings.
Zirconium abrasives are a mix of aluminum oxide and zirconium. These abrasives have a higher metal removal rate than just aluminum oxide. Zirconium abrasives work well for high-quality grinding on stainless steel, carbon steel aluminum, titanium, and cast iron. Most commonly associated with metal sanding and grinding, zirconium is also great for heavy sanding on raw wood, rust, and heavy stock removal.
Silicon carbide abrasives are generally application specific. Having a higher metal removal rate than zirconium, these abrasives are commonly used on steel, cast iron, aluminum, and rubber products. Silicon carbide has been used for more than 100 years in grinding wheels and other abrasive applications.
Ceramic abrasives, being some of the strongest and sharpest abrasives, are very useful on aluminum and stainless steel. Ceramic does not dull as quickly as other abrasives due to its extreme toughness and self-sharpening capabilities. These abrasives provide outstanding grinding and finishing on a variety of different hard metals.
