When we discuss the properties of brown fused alumina abrasives, we often mention hardness, content, etc., including the different grades of brown fused alumina hardness mentioned in the previous article, and so on, but rarely mention another attribute of it-toughness. But in fact, the toughness of brown fused alumina is also a very important attribute.
First of all, to understand the concept of toughness, the toughness of abrasives refers to the ability of abrasive particles to resist fracture under the action of grinding force, and is an attribute of the ability of abrasives to resist impact and absorb energy.
If brown fused alumina has certain toughness, it will guarantee its own service life. At the same time, toughness has a great influence on the self-sharpness of brown fused alumina. The stronger the toughness, the less easily brown fused alumina is broken, but it is easy to passivate and grind. The power is reduced, and the two functions are mutually exclusive.
Of course, there is also a measure of the toughness of brown fused alumina, which cannot be extended indefinitely because of the contradictory nature of brown fused alumina toughness and self-sharpness. Therefore, it is necessary to determine the toughness and self-sharpness according to the needs of its own needs.
