Applications
   Applications:       
   Your choices are...         
   Abrasive Jet Cutting       Abrasive water jets cut sheet materials or to remove materials from a surface by generating a focused stream of fluid mixed with abrasive particles. Garnet grain is widely applied as the abrasive media in abrasive water jet cutting. Air abrasive jet cutters are employed in cutting softer materials or micro-cutting applications. Precision air abrasive blasters or micro-jets produce extremely fine and precise streams. They are used for drilling, detailing and precision cutting of printed circuit boards and other high quality components. The abrasive grains most commonly used in air systems are aluminum oxide or silicon carbide. 
   Blasting       Abrasive blast machines and sandblasters clean and prepare surfaces by directing a stream of abrasive particles against a part or a surface. Blast wheels, pressurized water or compressed air drive the abrasive or blasting media. Blasting is used for finishing, surface texturing, roughening, frosting / etching, degreasing, deburring, deflashing, descaling, stripping of coatings, and surface preparation of products made of metal, wood, plastic, glass or other materials. Aluminum oxide, coal slag, glass, plastic media, corncob, and nutshell are commonly used in blasting applications.  
   Blending & Intermediate Cutting       Abrasive products designed for blending or removing parting lines, seams, or other significant surface imperfections. Medium or medium fine grit products are typically used for light cutting or intermediate material removal applications. 
   Burnishing       Burnishing polishes and cleans parts without the use of abrasive compounds. 
   Cleaning / Surface Prep       Cleaning and surface preparation products are finishing media that are formulated for cleaning, degreasing, de-oiling, descaling, texturing, roughening, discoloration removal, and other surface preparation applications. 
   Coated Abrasives       Coated abrasives contain abrasive grains held together in a matrix of resin, rubber, or other binders. They are used to remove surface materials such as metal, ceramics, glass, plastics, and paint. Coated abrasives are used in both grinding wheels and abrasive stones or sticks. Coated abrasives use several different types of abrasive grains. Aluminum oxide, the most common industrial mineral in use today, is used either individually or with other materials to form ceramic grains. Aluminum oxide is also combined with emery and crocus to produce abrasives suitable for finishing applications. Other types of abrasive grains include garnet, tungsten carbine, silicon carbide, and alumina-zirconia. Super-abrasive diamond pastes are useful in ferrous polishing or lapping applications where heat and reactivity are not a factor. Cubic boron nitride (CBN), a superabrasive grain with hardness second to diamond and a cubic crystal structure, provides superior grinding performance on carbon and alloy steel. 
   Deburring / Deflashing       Abrasive products designed or suitable for removing burrs, sharp corners, part lines, and flash (deflashing). 
   Descaling / Stripping       Abrasive grit or media designed or suitable for decsaling or coating stripping applications.  http://205.153.241.230/P2_Opportunity_Handbook/section5.html 
   Fast Cutting / Aggressive       Coarse grit abrasive products are typically designed for heavy cutting or material removal applications. 
   Grinding / Ball Milling       Media designed for ball milling or grinding down of bulk, powder, or granular materials into finer powder forms. Typically, ceramic bead, hard metal shot, carbide balls, or other ball shaped media are used. The hardness of the powder or bulk material being ground will determine the selection of the media's material.  Ball milling processes can disperse or mix pigments or fillers into resins, paints, coatings, plastics, rubber or adhesives. Media grinding or ball milling is also used for mechanically alloying metal powders, which creates new alloys that cannot be formed through fusion processes. 
   Grinding Wheels / Bonded Abrasives       Bonded abrasives contain abrasive grains held together in a matrix of glass, resin, rubber, or other binders. They are used to remove surface materials such as metal, ceramics, glass, plastics, and paint. Bonded abrasives are used in both grinding wheels and abrasive stones or sticks. Grinding wheels are used in a variety of applications and industries, while abrasive stones or sticks are used for sharpening edges and honing internal or external surfaces Grinding wheels are used for metal removal, dimensioning, and finishing. They consist of an integral shank, pin, shaft, or mandrel that drives a mounted wheel or blades. There are many types of grinding wheels, some of which are numbered by the American National Standards Institute (ANSI). Straight wheels are simple, flat discs without any recesses, flaring, or cups. Type 5 wheels are recessed on one side. Type 7 wheels are recessed on both sides. Both flaring-cup and straight-cup wheels are commonly available. Tapered grinding wheels have a thicker cross-section at the bore. Cylindrical wheels feature a length that is equal to or greater than the thickness of the wheel. Depressed center wheels exclude the mounting hardware from the grinding process. Dish wheels often contain superabrasives. 
   Peening       Peening shot and beads consists of small metal balls or glass beads. Peening shot is used impart compressive stresses into the surface of part as well as deburr sharp edges without removing material. Induced compressive stress improves fatigue strength. 
   Polishing       Finer abrasive grains designed or suitable for precision surfacing applications such as polishing, honing, lapping, color buffing, brightening, or other high surface, smoothness finishing applications. The fine abrasive grit is incorporated in finishing compounds, coated abrasive lapping films, superfinishing bonded abrasive products and/or polishing compounds. Polishing compounds, pastes or creams contain very fine abrasives as well as waxes or oils. Polishing compounds produce highly lustrous, bright and buffed surfaces. Specialized non-abrasive chemical agents are also available for electropolishing or chemical polishing processes.  Color buffing produces a bright lustrous or polished surface. 
   Tumbling / Mass Finishing       Tumbling and mass finishing media is used to deburr, burnish, color, descale, polish, or clean parts and components during finishing processes. Tumbling and mass finishing media involve choosing finishing shapes and media for particular tasks. Finishing shapes include balls, cones, ballcones, wedges, pins, tapers, cylinders, cut wire, diagonals, angle cuts, diamonds, cubes, oval balls, eclipses or balls with flats, crushed grit, pyramids, triangles, and stars or tristars. Finishing media consists of metal, ceramic, plastic, natural, wood, nutshell, corncob, carbonate, mineral, and synthetic materials.

   Shape       
   Your choices are...         
   Balls / (Beads Spherical)       Media is a bead, ball or spherical shape.  
   Ballcones / Satellites       Ballcone or satellite media has a shape that is a combination of a ball and cone, or a ball combined donut or toroid. The term "satellite" is used because the media looks like a flying saucer, satellite or top. Ceramic or carbide satellites have the appearance of a very short, stubby cylinder with two hemispheres on each end. 
   Cones       Media has a cone shape.  
   Crushed / Irregular       Abrasive grit, nugget or media has a crushed or irregular shape.  Typically, the irregular or crushed shapes are very angular with sharp edges for abrading, cutting or grinding. Aluminum oxide, silicon carbide, nutshell, glass and mineral abrasives or grit typically have a crushed shape. 
   Cubes / Rectangular       Media has a peg, cube, or rectangular shape.  
   Cylinders / Cylindrical       Media has a cylinder, flat-ended pin or other cylindrical shape.

   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Angle Cut?       Cylinder or shaped media is cut at an angle such as 45º angle cut cylinders or 22º angle cut triangles. The "angle cut" shape provides a sharper or narrower edge that can finish an inside corner or recess. The ceramic media made be formed or molded into the shape, not physically "cut". 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Bulk Density:       Bulk density is the mass per unit area for a material taking into account internal porosity.  The bulk density is dependent on the theoretical density of 100% dense body and the actual level of porosity between abrasive or media particles.  Tap density and loose pack density are two types of bulk density used to understand particle shape, interparticle friction and flowability.  Loose packed density (LPD) or aerated density is the density of the powder or particulate body without any settlement, mechanical agitation, vibration, or tapping. Usually, loose packed density measurements are made by determining the mass of powder in a sample container of known volume. Tap or packed density is the density of the powder or particulate body after settlement from tapping, mechanical agitation, vibration, or light packing (not compaction or consolidation). Often, both loose packed and tap density measurements are made to determine the Hausner ratio, which is calculated by dividing the loose-packed density by the tap density. Carr index is also related to loose packed and tap densities. The Carr index and Hausner ratio provide an indication of flowability.

Material / Composition
   Material / Composition       
   Your choices are...         
   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 using chemical ceramic technology, but 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, which 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. 
   Boron Carbide       Boron carbide is a very hard abrasive often used to make sticks for dressing other softer abrasives. 
   Cerium Oxide       Cerium oxide is a softer abrasive used for polishing and planarization applications. 
   Chromium Oxide       Chromia or chromium oxide has a small crystal structure. 
   Porcelain       Porcelain materials are used for both useful industrial and ornamental applications. Traditional porcelain is made from a mixture of feldspar, clay (koalin), and flint. Porcelains can be made from aluminum silicate, magnesium silicate, or aluminum magnesium silicate-based depending on the raw materials or minerals selected. 
   Silica / Silicate       Abrasive grain or finishing media is 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. These sharp and easily fractured abrasive grains for abrading other non-metals such as the stone, glass, wood, and leather. SiC, like diamond, is susceptible to oxidation at higher temperatures. 
   Sol-gel Ceramic       Sol-gel ceramic abrasives typically consist of aluminum oxide with or without additional modifiers produced using a sol-gel and sintering process. The ceramic processing route results in a hard, dense abrasive with an extremely fine crystal size and outstanding grinding performance on a variety of workpiece materials. 
   Superabrasive - CBN       Cubic boron nitride (CBN) is superabrasive grain with hardness second to diamond and a cubic crystal structure. CBN provides super grinding performance on carbon and alloy steel. Diamond is not useful in grinding steel or ferrous alloys because carbon or diamond readily dissolves or reacts with iron. CBN is produced synthetically in a high temperature, high-pressure process anvil press a process similar to synthetic diamond production. 
   Superabrasive - Diamond       Synthetic diamond is produced synthetically in a high temperature, high pressure process anvil press. Diamond is superabrasive grain with the highest known hardness and a cubic crystal structure. Diamond is used for grinding nonferrous metals, ceramics, glass, stone, and building materials. Diamond is not useful in grinding steel or ferrous alloys because carbon or diamond readily dissolves or reacts with iron.  Diamond pastes are useful in ferrous polishing or lapping applications where heat and reactivity are not a factor.  Diamond is susceptible to oxidation at higher temperatures 
   Tin Oxide       Abrasive grain or finishing media consisting of a stannous oxide (tin oxide) material.  Tin oxide is a safer abrasive used for polishing glass. 
   Tungsten Carbide / Hard Metal       Crushed tungsten carbide grit is utilized in metal bonded products for abrasion of tough materials such as composites, fiberglass, reinforced plastics, rubber and other specialized materials. 
   Zirconia       Abrasive grain or finishing media consisting of zirconium oxide material. Zirconia is a very tough and wear resistant ceramic. 
   Specialty / Other       Other specialty, proprietary or patented abrasive grain, grit or abrasive material.
