Diamond Age is a materials science and engineering firm that focuses on the research and development of leading-edge anti-ballistic armor systems. Current research projects involve overstiochiometric near-net shaped titanium boride (TiB2.4) ceramics, functionally
What Are the Right Abrasives for Your Metal Removal …
Silicon Carbide Silicon carbide crystals are hard, thin and very sharp—in fact, the only materials harder than silicon carbide are diamond and cubic boron nitride. Unfortunately, silicon carbide’s hardness and shape make it brittle, so even though it cuts quickly, it also tends to break down a bit faster than other abrasives, especially under extreme forces.

Metallographic Abrasive Cutting
Silicon carbide is a very hard abrasive which fractures and cleaves very easily. Thus, silicon carbide is a self-sharpening abrasive and is more commonly used for cutting nonferrous metals. Bonding Material - The hardness and wear characteristics of the sample determine which resin system is …
Diamond Machining: Ultraprecision Machine Technology …
Unlike carbide or CBN (cubic boron nitride) tools, which have random grain structures, single-crystal diamond tools have a very clear and well-defined grain structure. When mounting the tool in its shank, tool manufacturers orient the tool so as to make optimal use of the hardest point of the diamond.
