Usually when we discuss the properties of brown aluminum oxide abrasives, we often mention hardness, content, etc. Different grades of brown fused alumina have different hardness, but rarely mention its other property-toughness. But in fact, the toughness of brown fused alumina is also a very important property. Then let's discuss what this toughness means for brown aluminum oxide.
First of all, let's understand what the concept of toughness is. The toughness of abrasives refers to the ability of abrasive particles to resist crushing under the action of grinding force. It is an attribute of the ability of abrasives to resist impact and absorb energy.
If brown aluminum oxide has a certain toughness, it will ensure its service life. At the same time, toughness also has a great influence on the self-sharpening of brown fused alumina. The stronger the toughness, the less likely brown aluminum oxide is to break, but it is easy to be blunted and the grinding force decreases. The two functions are mutually exclusive.
Of course, there is also a measure for the toughness of brown fused alumina, which cannot be extended infinitely, because of the contradictory properties of the toughness and self-sharpening of brown aluminum oxide, so it is necessary to determine the balance between toughness and self-sharpening according to one's own needs.
