GRAV-LON STANDARD COMPOSITIONS
Product Description Density Packaging
    Lbs/Cu Ft  
GL-3 Combines the fast cutting qualities of GL-65 with the high density fracture resistance of GL-33. Its greater weight gives it an excellent cutting force, increasing with load size. Able to develop low micro finishes on hard metal parts. 110-115 50# Box
GL-33 A medium cut, long life composition well suited for high energy equipment. Will develop smooth and bright finishes. A bauxite based formula containing no fused aluminum oxide. 110-115 50# Box
GLF-33 A general purpose high density composition having good wear life. GLF-33 is a very durable and fracture resistant composition able to stand up to pressures generated in large vibrators and high energy equipment. The greater weight per cubic foot of the high density composition allows faster radius and deburring of parts than standard compositions. 110-115 50# Box
GL-36 The fastest cutting of the high density compositions. Combines short time cycle with low micro finishes. 110-115 50# Box
GL-41 The most aggressive cutting media available. It gives great amounts of cutdown in short time cycles and still retains good wear characteristics. GL-41 leaves parts with a matte finish, but with proper compounding, the parts will be clean and free of oxide impregnation. Recommended for all heavy deburring operations. 95-100 50# Box
GL-44 A very hard, long lasting composition used for light deburring and fine finishing. GL-44 is used quite successfully in vibrators, as it retains its sharp edges and points for a long time. It gives parts a clean and bright finish. Also, GL-44 can be used as a carrier for abrasive compounds. 85-90 50# Box
GL-65 A fast cutting composition fitting between GL-90 and the ultra-fast cutting compositions. It provides a higher rate of metal removal than GL-90, with only a slightly higher media loss. GL-65 is recommended for obtaining short time cycles on medium and heavy burrs and will leave parts with a clean semi-matte finish. GL-65 gives excellent results in vibratory finishing equipment. Bulk weight is 85 to 90 pounds per square foot. 85-90 50# Box
GL-90 A highly versatile composition having good cutting action and long wear life. Available in a wide variety of shapes and sizes. GL-90 will work in a wide variety of deburring, de-flashing and radiusing applications. It will also do an excellent burnishing job. Can be used in all types of equipment. Bulk weight is 85 to 90 pounds per cubic foot. 85-90 50# Box
GL-N A non-abrasive, high density media used for burnishing and brightening metal parts. Very long lasting. Requires a break-in period to develop best finishes. Good for chemically accelerated processes. 115-120 50# Box
