Selecting the Best Abrasive for Your Needs

BELT MATERIAL TYPES

Aluminum Oxide is a brown colored mineral that is tough and durable and the most widely used abrasive grain. It is coated in the entire grade range and is most commonly used in the metal, wood, leather and shoe industries. 

Silicon Carbide is a shiny black, sharp, very hard mineral that is coated in the entire grade range. It is used for a wide range of non-ferrous metals such as brass, titanium, the finishing of stainless steel, shoe trades, extensively for sanding primer, sealer, and top coats of paint and clear finishes. It is also the most effective grain for removing primary metal scale.

Alumina-Zirconia is an alloy mineral of aluminum and zirconium oxide that is very effective for coarse grade stock removal of metal and wood. 

Ceramic Aluminum Oxide is a mineral that is neither sintered nor fused. Compared to conventional aluminum oxide, this white mineral is two to three times tougher. 

GRITS

Sandpaper is made up for various sized granules. The finer the granules, the higher the grit count; the larger the granules, the courser the grit and the lower the grit count. The grit and type of sandpaper you need to use depends on the intended application. If you are simply finishing or smoothing, you want to use an extra fine abrasive; something below 100 grit. If removing material, such as paint, varnish, or uneven blemishes, stay between 120 and 150 grit sizes. If shaping or evening out un-leveled surfaces, you want to use a course grit of at least 200.

ABRASIVE BACKINGS

Cloth-backed abrasives are renowned for their durability and tear resistance, making them ideal for heavy-duty applications. While paper-backed abrasives are light weight and lower cost compared to cloth backing abrasives. Paper-backed abrasives provide cost-effectiveness, flexibility, and conformability, ensuring effective sanding on contoured surfaces and delivers even cutting for delicate processes and finer grits. However, it does not provide the rugged durability of cloth backed abrasives.

COATINGS

Open coat refers to only a portion of the backing is covered with an abrasive grain. This type of coating reduces loading in coarser grits. The backing is covered 50%-70%, allowing more room for material buildup to expel from the grain. In closed coat the grain is applied evenly together without any voids in the coat. It delivers a longer life and infer finish and typically used in non-woodworking applications.
