LAPPING COMPOUNDS

American Lap Company's lapping compounds are manufactured to exact specifications so a consistent finish is produced.  We have our stock compounds listed below and make compounds to any specifications. 

American Lap Company lapping compounds come mixed with a petroleum base or water base lapping vehicle.  Our premium compounds come in one pound cans.

LAPPING ABRASIVES AND THEIR USES

Aluminum Oxide: Aluminum Oxide should be used on soft metals because of it's unusual grain structure, relatively high degree of hardness, sharpness and malleability.   Aluminum Oxide will also cut hardened steels up to Rc 62.  This compound is also adapted to the lapping of; machine  spindles, bearings, dies, precision tools, hydraulic valves, injectors, spools and bodies and has many more uses.

Silicon Carbide:  Silicon Carbide is only suited for the lapping of hardened metals due to its characteristics of extreme hardness and sharpness.  But because of its brittleness and tendency to break down into very sharp pieces, thus produces scratches.   Silicon Carbide's use is restricted to the lapping of most gears and large valves.

Boron Carbide:  Boron Carbide is a very hard abrasive and is used for the lapping of materials with a high degree of hardness.  Typical applications are for the lapping of carbides, ceramics and very hard tool steels.

Diamond:  Diamond Lapping Compound is used to quickly lap the most difficult to cut materials.  Diamond powders can be produced to very fine micron sizes therefore can produce finest finishes in difficult to cut materials. 

ALUMINUM OXIDE LAPPING COMPOUNDS

SILICON CARBIDE LAPPING COMPOUNDS

BORON CARBIDE LAPPING COMPOUND

DIAMOND LAPPING COMPOUND

Diamond Compound packaged in 1/4 pound and 1 pound cans.

American Lap Company Diamond Lapping Compounds are precision graded and offered in different concentrations making it cost effective.  The compounds are color coded for easy identification and come in 5 or 10 gram syringes.   The Diamond Lapping Compound can also be packaged in jars or tubes.

BEAVER ECONOMY LAPPING COMPOUND

Beaver Lapping Compound is a silicon carbide grease base lapping compound.  Silicon carbide is a very sharp pointed abrasive grain that continually breaks down to leave a fine finish.  The petroleum base vehicle keeps the abrasive in suspension therefore no mixing is required.  Typical applications are: automobile valves, gears, blade sharpening and some precision lapping.    The compound is available in 1 pound cans (6 per case) 2000ml pails and 5 gallon pails.  To order 2000ml pails add "2000ml" to part number.  To order 5 gallon pails add " 5gal" to part number.
