Sintered corundum grains are made of special alumina, rare earth oxides as additives, sintered at high temperatures. The crystalline grains are 2~5um. As abrasive grains exhibit high strength and hardness，bonded by resin to produce heavy load grinding wheel.
ROYMT has developed grains of rod shape(SR-A) and triangular plate(SR-P).
Mainly used to build heavy load grinding wheel for rough grinding in steel factory.

For SR-A and SR-P，the regular ratio of length and diameter are list in above table, if customer has special requirement, we can provide grains according to your request.
