Standard: AE-17T

It is one kind of specially Brown Aluminium Oxide grain for abrasives application. The lumps that we used to be broken the grain is smelted by the different type of furnace, it is called "tilting furnace". This kind of product have the very small crystal in every abrasives grain, the toughness and anti-impact ability is much better than AE-17, but the cost is much lower than AE-17H. It is suitable for making vitrified bonded grinding wheels.
