The "Bite" in Coated Abrasives

Abrasive Grains perform the job of grinding, finishing and polishing. The ideal abrasive grain offers maximum resistance to point wear, yet fractures before serious dulling occurs, thereby satisfying both stock removal and finish requirements.

Aluminum Oxide - Man Made Abrasive

ALO

The most popular of all abrasives, aluminum oxide is extremely tough and has a wedge shape for high speed penetration of tough materials without excessive shedding or fracturing of the grain. Aluminum oxide is suited particularly well for grinding high tensile strength materials such as carbon steels, alloy steels, tough bronze and hard woods. Aluminum oxide is used whenever toughness (the ability to resist fracturing) is the main consideration. Aluminum oxide products are typically brown in color.

 

Silicon Carbide - Man Made Abrasive

Placeholder ImageNext to diamond in hardness, silicon carbide, characterized by its sharp sliver-like grains makes it superior for its ability to penetrate with light cutting pressures. It is primarily used for grinding nonferrous materials such as brass, copper, bronze and aluminum. Other applications of silicon carbide include grinding of glass, wood, rubber and plastics. It is used also to finish polyurethanes, primers, lacquers and sealers. Silicon carbide is the grain of choice for certain finishes on stainless steels. Silicon carbide products are typically black in color.

 

 

 

 

Zirconia Alumina - Man Made Abrasive

Placeholder ImageA blocky shaped grain that has a micro-crystalline structure, and is characterized as being self-sharpening. This self-sharpening characteristic gives zirconia alumina good life on heavy stock removal applications. Zirconia alumina is well suited for heavy grinding of metals and for planing operations for wood because of its controlled fracturing that exposes new, sharp cutting edges. Available in grits 24 through 150. Zirconia alumina products are typically blue or green in color.

 

 

 

Ceramic Alumina - Man Made Abrasive

A break-through in abrasive grain technology that far exceeds the perforance of nearly all other abrasives in certain applications.Individually grown abrasive grains that are two to three times tougher than Aluminum Oxide this abrasive’s crystalline structure is more uniform than abrasives manufactured by conventional fusing. It has applications in most converted forms of Coated Abrasives particularly where high stock removal is desired.

Garnet - Natural Abrasive

Garnet is a natural abrasive made by crushing garnet crude. Garnet is a soft mineral and is not as hard, nor as durable as the various man made abrasives. Garnet fractures along the cleavage lines of the crude crystals, exposing very sharp cutting edges as the grains fracture. Garnet is used in the wood working industry, particularly in finishing operations. Garnet is the recommended abrasive if you are getting burning of the wood with other abrasives.

Garnet is not suitable for use on metals.

Emery - Natural Abrasive

Emery is a natural abrasive that has a dull black color and used for general maintenance and polishing of metals in very fine grits for highly technical polishing such as metallurgical samples.

Crocus - Natural Abrasive

Crocus is essentially iron oxide particles and used mostly for cleaning corroded surfaces of polished metals. Crocus is also used for polishing gold and other soft metals.
