Uses and Specifications of White Fused Alumina

Bonded Abrasives: Bonded abrasives are made of natural or synthetic abrasive grains bound together with a vitrified or resinoid or other bonds into a mold, usually in the shape of a wheel, then pressed and fired at high temperatures. Bonded abrasives, which can be made from different materials, come in thousands of shapes and sizes depending on the type needed and specific application required, such as cutting-off and grinding wheels, snagging wheels, mounted wheels, segments, honing stones, plugs, cones, etc.

Blasting: Abrasives are used as blasting media to clean or prepare surfaces before applying coatings or to produce the desired surface profile by propelling wonderful bits of material at high-velocity. 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.? Any small, relatively uniform particles will work, such as steel grits, copper slags, walnut shells, powdered abrasives, even bits of coconut shells.

Cleaning/ Surface Prep: Abrasives are used as finishing media for cleaning and surface preparation products, applied for cleaning, degreasing, de-oiling, texturing, descaling, discoloration removal, roughening, and other surface preparation applications.

Coated Abrasives: Abrasive grains are used to make coated abrasives such as sandpaper and are available in sheets, discs, rolls, belts, pads, flap wheels, and other forms. Coated abrasives are a product of three essential elements: abrasive grains, bond, and backing. Abrasive grains can be either natural or synthetic, such as aluminum oxide, silicon carbide, zirconia alumina, garnet, emery, etc. The abrasive grain adheres to a cloth, fiber, paper, or polyester film backing by a resin or glue or another bond. Abrasive grains should exhibit high capillarity for instant adhesion to bonds.

Deburring/ Deflashing: Abrasives are designed or suitable for applications such as removing burrs, sharp corners, part or welding lines, and flash (deflashing).

Descaling/ Stripping: Abrasive grits or media? Are designed or suitable for descaling or coating stripping applications.

Fast Cutting/ Aggressive: Coarse grit abrasives are typically designed or suitable for fast cutting and aggressive applications such as heavy-duty cutting or hard materials removal.

Grinding/ Ball Milling: Abrasive media are applied for ball milling or grinding down a solid material or powder into smaller pieces or finer powders. The material is crushed. The media (ceramic bead, hard metal shot, carbide balls, or other ball-shaped media) are filled in the ball mill for rotating, grinding, and mixing by mechanical forces. The hardness of the material or powder being ground determines what kind of media material will be selected. Media grinding or ball milling is widely used in producing cement, silicate, new-type building materials, fireproofing, chemical fertilizer, black and non-ferrous metal, and glass ceramics. Besides, it is also used to make alloys from metal powders.

Polishing/ Lapping: Finer abrasive grains are used to make polishing/lapping compounds, coated abrasive lapping films, superfinishing bonded abrasives, etc. Polishing and lapping are characterized by excellent surface finishes, high dimensional accuracy and flatness, and minimal subsurface damage. They are the precision processes applied for mechanical and electronic or semiconductor components to produce a smooth, bright and lustrous surface.

Refractory: Abrasive grains with excellent chemical stability and thermal property, such as fused mineral brown fused alumina, have hundreds of different applications as refractory materials due to their ability to withstand continuous exposure to the combination of heat, corrosion, abrasion, and impact.?

Tumbling/ Mass Finishing: Abrasives are used or for the fabrication of tumbling and mass finishing media for the applications of deburring, burnishing, coloring, descaling, polishing, or cleaning for parts and components during finishing processes. The selection of shape (such as ball, cone, balcony, wedge, pin, taper, cylinder, cut wire, diagonal, angle cut, diamond, cube, oval ball, eclipse or ball with flat, crushed grit, pyramid, triangle, and star or tristar) and material (such as natural and synthetic abrasive grain, metal, ceramic, plastic, wood, nutshell, corncob, carbonate or mineral) of tumbling and mass finishing media should be selected depending on particular tasks.
