    High-Strength Fracture- and Wear-Resistant Zirconia Ceramic Balls

    Image of Product. Front orientation. Ceramic. High-Strength Fracture- and Wear-Resistant Zirconia Ceramic Balls.
    Often used instead of metal in bearings and rollers, these balls are ideal for applications where strength under heavy loads and wear resistance is needed. It's the addition of yttria that gives this zirconia more strength and lowers the chances of cracking from impact than standard zirconia, alumina, and silicon nitride ceramic. If cracks do occur, they will not spread, extending the life and reliability of the material. It also means this zirconia blend resists wearing down from rubbing against another part or abrasion from chemical slurries.
    These balls do not withstand rapid temperature changes or high temperatures as well as other high-performance ceramics such as ceramic alumina and silicon nitride ceramic.

    Tumbling Media for Steel, Stainless Steel, and Hard Metals

    Image of Product. Front orientation. Tumbling Media. Tumbling Media for Steel, Stainless Steel, and Hard Metals, Ball.

    Ball

    Made of a hard material, this tumbling media is tough enough to finish steel, stainless steel, and other hard metal parts. Choose the shape that best matches the contours of your part and a size that’s large enough not to get stuck in recesses and holes. You can also mix shapes and sizes to tailor the finish to your part.
    For Mirror Finish—Use this media as the final step in your finishing process to create a reflective finish. Ideal for fragile parts, it rubs the surface without removing material.
    Ball—Best for gentle finishing. Balls are less aggressive than other shapes, so they smooth your workpiece without flattening any details.
    Wet Tumbling Condition—Use this media with liquid cleaners.

    Acid-Resistant Silicon Carbide Ceramic Balls

    Image of Product. Front orientation. Ceramic. Acid-Resistant Silicon Carbide Ceramic Balls.
    Extremely hard with excellent corrosion resistance, this silicon carbide ceramic is often used for rubbing parts such as bearings and bushings in chemical-processing environments. This material’s hardness means it resists abrasion and wear, but also makes it more brittle than other ceramics. Don’t use it under heavy loads or at high speeds. Nearly chemically inert, it resists corrosion better than other ceramics when in contact with acids and other chemicals. Silicon carbide ceramic conducts heat well and doesn’t expand significantly from heat, so it won’t deform or crack from temperature swings. Rated for use at up to 2550° F, it’s good for use in furnaces and refractories.

    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.
    Ceramic Bead
    Image of Product. Front orientation. Abrasive Blasting Media.
    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.
    High Reusability—Effective for hundreds of cycles under normal blasting conditions.
