Material / Composition
           
   Your choices are...         
   Aluminum       Abrasive grain or finishing media consisting of aluminum shot, cut aluminum wire, or cast aluminum shot. 
   Aluminum Oxide       Aluminum oxide is the most common industrial mineral in use today. Fused aluminum oxide is produced synthetically by melting bauxite and an additive in an arc furnace to form a fused aluminum oxide ingots, which are later crushed and sized. Fused aluminum oxide is also produced synthetically by chemically purifying. The various types of fused aluminum oxides are distinguished by the levels of chemical impurities remaining in the fused mineral. Titanium and chromium oxides are typical additives. Other techniques to make an industrial abrasive start with treating bauxite ore with a sol gel process to create alumina that is sintered to produce with an extremely fine crystalline structure typical of the sol gel or Seeded Gel products available by Saint Gobain Abrasives. Fused aluminum oxide is available in several variations depending on composition and processing such as white (high purity), brown or regular (titanium oxide modified), and pink (chromium oxide additions). Titanium oxide additions can toughen the abrasive and enable heat-treating process, which changes brown aluminum oxide to a blue-colored grain as titania precipitates form. Aluminum oxide abrasives are also produced with chemical precursors and precipitation, calcination and/or sintering processes. Calcined or platelet alumina as used in fine grit or polishing applications. Sol-gel aluminum oxide is produced in using chemical ceramic technology, but this abrasive has very high performance and is usually referred to as Ceramic abrasive grain to distinguish the grain from lower-performing fused aluminum oxide. Aluminum oxide occurs naturally in the form of the mineral corundum, but the mineral is not used as a commercial abrasive except as a component of emery. 
   Alumina-Zirconia (e.g.,  Norzon®)       Alumina-zirconia abrasive grain consists of a fused alloy of aluminum oxide and zirconium oxide.  NorZon® is widely used variation proprietary to the Norton Company that consists of a fused and quenched eutectic mixture of aluminum oxide and zirconium oxide.  The resulting fine structure and higher hardness contributes to improved grinding performance on stainless steel, titanium, and other exotic metals. 
   Carbonate (Sodium / Calcium)       Abrasive grain or finishing media consists of sodium bicarbonate (baking soda) or calcium carbonate (Aragonite, Calcite, chalk, limestone).

   Ceramic       Ceramic and inorganic abrasives and media include aluminum oxide, silicon carbide, zirconia, silicate, fused silica, boron carbide, synthetic diamond, CBN, tin oxide, tungsten carbide, and cerium oxide.  The ceramic abrasives are dense abrasives with outstanding grinding and finishing performance on a variety of workpiece materials. Hardness of ceramic and inorganic abrasives and media varies with specific composition. Diamond, boron carbide, and CBN are among the hardest materials and are used to grind and finish very hard ceramic and alloys.  
   Chromium Oxide       Abrasive grain or finishing media consisting of fused chromia or chromium oxide, which has the small crystal structure as aluminum oxide with higher hardness. 
   Corn Cob       Abrasive grain or finishing media consisting of the soft woody ring of a corncob. Corncob is a very soft and low aggressive media for blasting or coating removal. Soft metal, wooden, plastic, or composite parts can be cleaned of have coatings stripped off without damage to the underlying substrate. 
   Garnet       Garnet is a natural silicate mineral, consisting of a combination of Almandite and Pyrope, which mined from igneous mineral deposits or in concentrated pockets of alluvial deposits of old riverbeds. Garnet has the general chemical formula of Fe2O3Al2 (SiO4)3.  The iron and aluminum are partially replaceable by calcium, magnesium, and manganese. 
   Glass       Abrasive grain or finishing media consisting of glass. Glass is a fused silica-based material solidified into an amorphous state. Glass fractures into shapes produce very sharp edges; however, the edges may not be as hard or durable compared to crystalline minerals or synthetic aluminum or silicon abrasives.

   Metal       Metal abrasives and media includes metal shots or balls, cut wire, crushed metal grit, or shaped media for blasting, ball burnishing, peening, mass finishing (vibratory or tumbling), deburring, bonded wheels, coated abrasives, or other applications. Steel, stainless steel, cast iron, aluminum and zinc are commonly used alloys. 
   Plastic       Abrasive grain or finishing media consists of plastic material. Both thermoplastic and thermoset resins are used to produce plastic media and plastic grit.  Thermoset resins are more resistant to softener or heat damage.  
   Pumice       Abrasive grain or finishing media consisting of pumice. Pumice is a silica-based, volcanic (pyroclastic igneous) rock with a very porous structure. Pumice is used block form for sharpening or cleaning.  Pumice is also ground into a powder for polishing and cleaning applications. 
   Silica / Silicate       Abrasive grain or finishing media based on silicon dioxide or silica. Fumed silica is often used in semiconductor or silicon-wafer polishing and planarization applications. A pure silica CMP compound does not impart poisons or impurities into the wafer fab process. Typically, fumed or amorphous silica abrasives are chosen because crystalline silica is considered carcinogenic. Silica and silicate materials include fused silica, quartz, koalin or clay based materials, cordierite, steatite, forsterite, sillimanite, zircon, porcelain, and fireclay. 
   Silicon Carbide       Silicon carbide (SiC) is a synthetic abrasive first developed in the late 1800s. SiC is harder than aluminum oxide, but more friable than fused aluminum oxide grains. Silicon carbide is typically applied to nonferrous applications (brass, aluminum, titanium).  The high solubility of carbon and silicon in iron would result in a reaction of silicon carbide with the iron base alloy and poor grinding performance.  Levels and types of impurities distinguish the green and black forms of silicon carbide. The sharp and easily fractured abrasive grain is used for abrading other non-metals such as the stone, glass, wood, and leather. SiC, like diamond, is susceptible to oxidation at higher temperatures. 
   Slag / Coal Slag       Abrasive grain or finishing media consisting of slag residues from coal burning processes. 
   Sponge / Foam       Abrasive grain or blasting media consisting of abrasive grit in a larger polyurethane sponge or foam particles. Sponge or foam blasting media is often used wet and can absorb liquids during the blasting process.

   Steel       Steel media is often in the form of steel shot, steel peening balls, or cut steel wire. Crush steel alloy grit is a less common form. 
   Synthetic       Abrasive grain or finishing media made of a synthetic or fabricated material consisting of a polymer matrix highly filled with silica or alumina. Filler synthetic media has a lower weight compared to ceramic media with lower hardness. Synthetic media has higher hardness and aggressiveness compared to plastic media. 
   Tripoli       Abrasive grain or finishing powder consists of a natural silicate or siliceous limestone mineral called tripoli or rottenstone. Tripoli is most commonly ground into a powder and used for polishing or in finishing compounds. 
   Type I (Polyester)       Type I plastic abrasives are based on a thermoset polyester resin. Types I have a hardness of about 3.0 Moh. These plastic abrasives are generally used for removing paints from soft aluminum or copper. 
   Type II (Urea)       Abrasive grain or finishing media consisting of urea thermoset plastic resin. Urea thermoset resins tend to be harder (3.5 MOH Hardness), are more resistant to softening, and are more aggressive compared to acrylic or polyester types. Urea or type II plastic abrasives are the most commonly used type. Urea type II abrasives are the fastest media for coating or paint stripping on aircraft, trucks, trailers, tractors, rail cars, vans, motor homes, marine vessels, cars, buses. The U.S. Air Force has approved this plastic abrasive for use in stripping coatings, paints, surface sealants, or powder coatings from airframes, aircraft engine components, automobiles, buses, and truck bodies. They are also useful for mold cleaning. 
   Type III (Melamine)       Abrasive grain or finishing media consists of melamine or type III thermoset plastic resin. Melamine thermoset resins are the hardest plastic abrasives used  for providing the fastest and most aggressive plastic blasting abrasive available.  Melamine type III plastic abrasives are aggressive enough to replaces glass beads and other harsh abrasives in certain applications.  Melamine type III plastic abrasives are useful in cleaning and stripping difficult-to-remove paints, residues and primers from hard materials such as engine parts, turbine blades, molds, metal die castings, steel gears, tire molds, axial lead diodes, capacitors, clear optical sensors, computer housing panels, copper armature wires, and actuator assemblies.  
   Type IV (Phenolic)       Type IV plastic abrasives consist of a phenolic or phenol formaldehyde resin composition. Phenolic is a thermoset plastic. Types IV and V have higher hardness (3.5 Moh hardness) and are useful in removing coatings and paint from hard aluminum and steel. Type IV plastic media is not widely used or available compared to other plastic abrasive types. 
   Type V (Acrylic)       Type V plastic abrasives are based on acrylic thermoplastic composition with a hardest range (3.2-3.5 MOH Hardness), lower than urea (Type II) and melamine (Type III) plastic abrasives. While not the most aggressive type, acrylic type V plastic blasting abrasives are the most durable or longest lasting type. Type V acrylic blasting media is more forgiving compared to other plastic media types. Type V acrylic blasting media applications include paint stripping of aircraft structures, trucks, trailers, tractors, rail cars, vans, motor homes, marine vessels, cars, and buses, airframes, aircraft components, fiberglass components, aluminum and magnesium parts, carbon graphite composites, axial lead diodes, capacitors, clear optical sensors, computer housing panels, copper armature wires, die castings, and actuator assemblies. Acrylic is a thermoplastic resin. Thermoplastic resins are softer and gentler on a surface, which may limit substrate damage during coating removal or paint stripping. Thermoplastics can be remolded and recycled more easily. 
   Type VI (e.g., Clear-Cut®)       Type VI plastic abrasives are based on a polyallyl diglycol carbonate thermoset resin. Clear-Cut® plastic stripping abrasives are well known examples of Type VI materials. Clear-Cut®  is registered trade mark of Composition Materials Co., Inc. 
   Type VII (Biodegradable)       Type VII plastic blasting media has the lowest hardness (2.0-2.8 Moh hardness). These very soft abrasives are used on surfaces such as fiberglass and soft metals. Type VII plastic abrasives are composed of a nonpetroleum amylaceous polymer, which biodegrades when released into the environment.
