Blasting Media

Because we rely on a worldwide base of reputable suppliers, you’re assured of consistent high quality and delivery as well as competitive prices. It’s what companies like yours expect from Grand Northern Products: the best media combined with the most effective process for your application.

Glass Bead All-purpose media Hones, polishes, peens, blends, finishes, removes light burrs, or cleans light foreign matter (e.g., carbon or surface residues from pistons and valves) Can be used to detect weld and solder flaws Available in a wide range of sizes (screens)

Ceramic Shot Dustless Cleans, satin finishes, deburrs, and tumbles. Exceptional working life Can be used for stainless steel and nonferrous metal surfaces. No subsequent decontamination required Excellent for stainless steel weld cleaning

Steel Shot Causes a peening action and produces a dimpled surface Peens and cleans heavy forgings and removes heat-treating scale

Steel Grit Cleans quickly Ideal to prep surface for a new coating Can be mixed with grit to achieve unique finishes

Brown Aluminum Oxide Extremely fast cutting Can produce an “anchor” pattern to prep for recoating Removes heavy foreign matter, deburrs, frosts glass and letters stone Can be reused many times Available in a wide range of sizes Available in a wheel grade grain (produced to grinding wheel specifications), which is used in tight tolerance blasting, lapping, or where iron levels or dust are of concern

White Aluminum Oxide Used primarily in the production of grinding wheels and honing stones Used when iron contamination is a concern or as a refractory material in the investment casting process Blasting applications include dental labs and aerospace parts

Black Silicon Carbide Hard, sharp abrasive Used in grinding wheels, honing stones, coated and loose abrasive applications

Green Silicon Carbide Specialty grain Used almost exclusively in the manufacturing of grinding wheels, mounted points and honing stones

Crushed Glass Sharp, more aggressive media Used when glass chemical properties are desired

Plastic Media High tensile, compressive and flexural strength, combined with comparatively low hardness Deflashes plastic parts and cleaning molds, dies, electronic connections and circuit boards Deburrs machined-iron castings and nonferrous screw machine parts

Walnut Shells Removes foreign matter or coatings without etching, scratching or marring the cleaned areas Cleans delicate molds, armatures and electric motors prior to rewinding

Corn cob Soft-grit blasting material Removes light foreign matter such as carbon, oil and dirt without affecting surfaces

Baking soda Soft, single pass media Cleans and depaints machines, dies, molds, and presses Degreases and strips almost any material without substrate damage

Jet Mag Used in replacement of Silica Sand.

Novaculite Used primarily for wet blast applications
