When we usually discuss the properties of brown aluminum oxide abrasives, we often mention hardness, content, etc. Different grades of brown aluminum oxide have different hardness, but rarely mention its other property - toughness. But in fact, the toughness of brown aluminum oxide is also a very important property. Next, let's discuss what the toughness means to brown fused alumina.
First, let's understand the concept of toughness. The toughness of abrasives refers to the ability of abrasive particles to resist breaking under the action of grinding force. It is a property of the abrasive's ability 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 aluminum oxide. The stronger the toughness, the less likely the brown fused alumina 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 aluminum oxide, which cannot be extended infinitely, because of the contradictory properties of the toughness and self-sharpening of brown fused alumina. Therefore, it is necessary to determine the balance between toughness and self-sharpening according to one's own needs.
