Abrasive Particles Used For Grinding Wheels Industries

Al 2 o 3 is therefore very suitable for grinding materials of high tensile strength 2700 kgfcm 2 if al 2 o 3 be used with material of low tensile strength then resistance offered by the material on grinding wheel will be less in such case abrasive particles do not fall off from the wheel and keep on getting blunt so grinding will be poor.
