Abrasives-Corn Cob

Abrasives-Corn CobIn tumbling and vibratory finishing applications, the primary purpose for using corncob grit is to dry metal parts. However, corncob can also deburr and polish parts such as:

  • Ball bearings
  • Pipe fittings
  • Nuts and bolts
  • Computer chips
  • Springs
  • Metal die castings
  • Wire brads
  • Optical glass
  • Cutlery
  • Buttons
  • Jewelry
  • Rivets
  • Molded plastics
  • Golf club heads

The grades most often used are 1014 (#1), 1420 (#2), and 2040 (#3). Also consider using one of our additives to achieve a high luster finish.

CRW proudly sells processed corncob grit that is the most accurately screened, sized and air-washed corn cob media available in the market today and boasts the lowest moisture content typically at 4 - 6%, maximum 10%. This allows for more absorption of oil, cleaning fluids or other liquids during the finishing process.

Our corn-cob is organic, non-toxic, biodegradable and a USDA Bio-Preferred Product - an effective, eco-friendly option for your abrasive media needs. It's tough enough for soft-grit blasting yet gentle enough for health and beauty products.

Other applications include:

  • Absorbing oils, greases and dirt from manufactured pieces
  • Barrel or bowl finishing and removal of burrs
  • Absorbing rinse waters remaining on electroplated pieces in tumbling dryers
  • Silica-free soft grit blasting for cleaning carbon, oil and products of corrosion from cylinders, pistons and other engine/electric motor parts
  • Silica-free soft grit blasting of log homes resulting in the cleaning and refinishing of natural wood homes
