Detailed Product Description:

Aluminum oxide is an angular, durable blasting abrasive and thus

can be recycled many times.  It is the most widely used abrasive

in blast finishing and surface preparation because of its relatively

low cost, longevity and hardness. 

Aluminum oxide grit penetrates and cuts even the hardest metals

Including sintered carbide.  It is about half the weight of metallic

Media with twice as many particles per pound.  The resulting fast

cutting action minimizes damage to thin materials by eliminating

surface stresses common with heavier, slower cutting media.
 
Only virgin, brown aluminum oxide is recommended for optimal performance

rather than reprocessed or remanufactured product.  Virgin, brown aluminum

oxide contains less than 1.5% free silica and is therefore safer to use than

sand.  The grit size is consistent and cuts much faster than sand, leaving a

smoother surface.  Generally, the larger the grit size, the faster it will cut.

Application Notes:

Aluminum oxide grit has a wide variety of applications, from cleaning

turbine blades in the aircraft industry to lettering in monument and

marker inscriptions.  It is also commonly used for matte finishing,

as well as cleaning and preparing parts for metallizing, plating and

welding.  Aluminum oxide is the best choice for preparing a surface

for painting.

Suggested Air Pressure:                                  80-90 PSI max.

Grit Size:                                                              #60 mesh size

Hardness:                                                             9 Moh  (Diamond = 10)      

Precautions:

Be sure to wear appropriate respiratory protection.

Not recommended for surfaces which are to be left uncoated in use.

Abrasive particles can become imbedded and later sloughed off into

moving parts such as bearings.

Packaging:

Comes packed in 50 pound bag.
