Abrasive Blasting Media

Remove paint, coatings, and rust or add texture to surfaces. This media is suitable for use on a wide variety of surface materials.

Our abrasive blasting materials are sorted from least to most aggressive. The more aggressive the media, the more material it removes from your surface.

Both particle mesh size and grit measure the size of the abrasive particles. The higher the number, the finer the particles are.

Steel Shot

The most common abrasive for heavy duty cleaning and peening jobs. Rounded like glass but harder and denser, this shot blasts away heat-treated scale, heavy forgings, and other stubborn irregularities while leaving a uniformly peened finish. It also lasts for 500 times more cycles than glass, so it’s perfect for abrasive blasting cabinets and other systems that let you reuse your media.

High Reusability—Effective for hundreds of cycles under normal blasting conditions.

Stainless Steel Shot

Just as aggressive as steel shot but with better corrosion resistance and durability. Unlike steel, this shot cleans and peens stainless steel, brass, and other nonferrous metals without contaminating them with iron. It also stays effective for twice as many cycles as steel shot. This high-impact shot isn’t recommended for removing paint from aluminum and plastic.

Very High Reusability—Effective for thousands of cycles under normal blasting conditions.

Ground Glass

A more aggressive alternative to glass bead, this angular abrasive blasts harder and leaves a rougher finish. It’s most often used to clean bricks, cement, and other masonry that’s already rough. While moderately aggressive, it’s still gentle enough to etch aluminum, plastic, and other soft materials without gouging them.

Not Reusable—Typically only effective the first time it's used.

Coal Slag Grit

Also known as black diamond, this media is the most widely used grit-style abrasive. Known for its use in sandblasting, its sharp, angular shape etches a wide range of surfaces. It won’t leave behind contaminants. A lower-cost alternative to Black Beauty grit, it produces a less uniform finish. It’s not recommended for removing paint from aluminum and plastic.

Not Reusable—Typically only effective the first time it's used.

MIL-A-22262B—This grit meets strict standards for particle size, material quality, and hazardous waste. It’s certified to remove enough scale, rust, and paint to prep metal surfaces and doesn’t contain more than 1% free silica.

Black Beauty Grit

A step up in finish quality from coal slag grit. Every lot is tested and certified to exceed the standards of MIL-A-22262B, so it produces a uniform finish and contains less than 0.1% free silica. Sharp, angular edges etch a wide range of materials—everything from aluminum to stainless steel to wood. This grit produces less dust than coal slag grit due to its strict processing. Any dust it does leave behind won’t contaminate surfaces. It’s not recommended for removing paint from aluminum and plastic.

Not Reusable—Typically only effective the first time it's used.

Steel Grit

A more aggressive alternative to steel shot, steel grit blasts harder and leaves a rougher finish thanks to its sharp, angular edges. It digs below the surface to remove material, which is why it’s commonly used to strip paint, remove rust and scale, and prep surfaces for coatings to bond to. However, you should only use it on steel and iron surfaces because it will leave iron behind that could contaminate other materials.

Medium Reusability—Effective for dozens of cycles under normal blasting conditions.

Garnet Grit

An economical choice for grit-style abrasive. It’s not as reusable or abrasive as aluminum oxide grit, so it’s commonly used to clean masonry where it would be difficult to reclaim your media.

Low Reusability—Effective for a handful of cycles under normal blasting conditions.

Aluminum Oxide Grit

The grit you think of for sanding, grinding, and polishing. As abrasive blasting media, aluminum oxide grit does it all—from blasting away paint to frosting glass to deburring and etching metal. It’s hard and has sharp, angular edges for fast cutting. It won’t leave behind contaminants like steel grit, so it can be used on a wider variety of materials.

Silicon Carbide Grit

Quickly cleans granite, ceramics, silicon, quartz, cemented carbides, and other tough materials. However, it is more brittle than aluminum oxide grit, so it sheds more dust.

Bauxite Bead

A step up in hardness and durability from glass bead. This round abrasive lightly peens metals that are too hard for glass bead, such as steel and stainless steel. It's also a good middle-ground, cost-wise, between glass and ceramic bead—it’s more expensive than glass bead because it stays effective for 200 times more cycles, but it’s not as expensive as long-lasting ceramic.

High Reusability—Effective for hundreds of cycles under normal blasting conditions.

Ceramic Bead

The hardest, longest-lasting bead abrasive we offer. This round abrasive stays effective for 500 times more cycles than glass bead while delivering the same smooth finish. Since it’s harder than glass and bauxite bead, it easily peens steel, stainless steel, and other hard metals. It’s also virtually dust-free, so you'll find it used in medical, aerospace, and other dust-sensitive environments.

Ceramic Grit

Your pick for long lasting, dust-free grit. It lasts for 500 times more cycles than aluminum oxide while leaving a similar finish. It’s also virtually dust-free, so you'll find it used in dust-sensitive environments such as medical and aerospace spaces.

Abrasive Blasting Media for Delicate Materials

Remove paint, coatings, and rust from delicate materials. Softer than other abrasive blasting media, this media cleans away contaminants without scratching or marring the underlying surface. It is a good choice for finishing soft metals, plastics, wood, or sensitive equipment.

Our abrasive blasting materials are sorted from least to most aggressive. The more aggressive the media, the more material it removes from your surface.

Both particle mesh size and grit measure the size of the abrasive particles. The higher the number, the finer the particles are.

Corn Cob

Clean without abrasion—corn cob is gentle enough to clean wood, fiberglass, plastic, and masonry without causing damage. It won't frost glass, pit aluminum, or raise grain on wood.
