Description:
used for production of the premium quality portable wheels, steelconditions wheels and cut-off wheels.Description:
AEHTT isa kind of medium bulk density fused Brown Aluminum Oxide abrasivespecially heat-treated under carefully controled time, temperatureand atmosphere.
The hightemperature heated then cooling is to renovate the crack on thesurface and interior of grain crystal and then to improve thetoughness and durability of the grains.
As atough and strong abrasive, AEHTT can obviously bring rapid stockremoval with minimal abrasive wear.
Applications:
AEHTT iswidely used for production of the premium quality portable wheels,steel conditions wheels and cut-off wheels.
