A group of abrasives first introduced in the early 1900s to become the most common abrasive used in wheels and coated abrasives. Ceramic abrasives, which are a recent innovation in abrasives, are sintered microcrystalline form of aluminum oxide.
Diamond and CBN abrasives are called ultra-hard abrasives because of the extreme hardness, "ultra" performance, and long life. Ultra-hard abrasives are developed during the second half of the 20th century. These premium abrasives contrast with more traditional "conventional" abrasives. The name, however, does not denote superior abrasive that can be applied universally. Conventional abrasives are clearly better for some applications.

What is the main application for ultra-hard abrasives?

Ultra-hard abrasives are mostly used to produce various tools such as diamond drill, diamond wheel and diamond saw. It is very important to select the correct products according to your specific need. Different ultra-hard abrasives are suitable to machining different workpiece, such as rock, granite, glass and alloy.
