When discussing the properties of brown fused alumina abrasives, the most mentioned is its hardness. The hardness of different grades of brown fused alumina is different, but the toughness of brown fused alumina is also a very important attribute. So the following Corundum Abrasive manufacturer will tell you what is the significance of toughness for brown fused alumina?
First of all, we must understand the toughness. The toughness of the abrasive refers to the ability of the abrasive to resist the fracture under the action of the grinding force. It is an attribute of the strength of the abrasive against impact and energy absorption. The brown corundum abrasive has certain toughness and can guarantee its service life. At the same time, the toughness has great influence on the self-sharpness of the brown corundum. The stronger the toughness, the less easily the brown corundum is broken, but it is easy to passivate. Of course, there is also a measure of the toughness of brown fused alumina, which cannot be extended indefinitely because of the contradiction between brown fused alumina toughness and self-sharpness.
